Write a recursive function sumSquares(num) that given an integer num, returns the sum of squares of numbers from 1 to num. For example: sumSquares(3) should return 1^2 2^2 3^2
Answer:
Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.
def sumSquares(num):
if(num >= 0): # checks if the value of num is less than or equal to 0
if (num==0): #if value of num is 0
return 0 #returns 0 if value of num is 0
else: #if value of num is greater than 0
return sumSquares(num - 1)+ num * num #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num
else: # if a user enters a negative num
(print("The number if not positive")) #prints this message
exit() # exits after displaying that number if not positive message
#below print statement is used in order to check the working of the function
print(sumSquares(3)) #calls function and passes value 3 for num
Explanation:
The program works as follows:
The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num
The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:
return sumSquares(num - 1) + num * num
For example num = 3
so the above recursive statement works as follows:
sumSquares(3-1) + 3 * 3
sumSquares(2) + 9
Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:
sumSquares(2 - 1) + 2 * 2 + 9
sumSquares(1) + 4 + 9
sumSquares(1) + 13
sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:
sumSquares(1 - 1) + 1 * 1 + 13
sumSquares(0) + 1 + 13
sumSquares(0) + 14
sumSquare() method is called again and the value 0 is passed as num
As the value of num=0 So the if (num == 0): condition evaluates to true and the statement returns 0 executes which returns 0:
sumSquares(0) + 14
0 + 14
Hence the output is:
14

Consider the following instruction: OR( %1111_0000, AL ) ; After its execution, what will be true about the bits stored in AL?
Answer:
the higher order bits in AL will be true
Explanation:
We know from the truth table that in an OR operation, once one operand is true the result is true, no matter the value of the other operand. From the above AL will have the higher order bits to be true since the first four higher order bits are 1s, 1111_0000, this is regardless of the original values of AL. We cannot however ascertain if the lower bits of AL are true from this. Note 1 evaluates to true while 0 is false
Write a Bash script that searches all .c files in the current directory (and its subdirectories, recursively) for occurrences of the word "foobar". Your search should be case-sensitive (that applies both to filenames and the word "foobar"). Note that an occurrence of "foobar" only counts as a word if it is either at the beginning of the line or preceded by a non-word-constituent character, or, similarly, if it is either at the end of the line or followed by a non-word- constituent character. Word-constituent characters are letters, digits and underscores.
Answer:
grep -R '^foobar'.c > variable && grep -R 'foobar$'.c >> variable
echo $variable | ls -n .
Explanation:
Bash scripting is a language used in unix and linux operating systems to interact and automate processes and manage files and packages in the system. It is an open source scripting language that has locations for several commands like echo, ls, man etc, and globbing characters.
The above statement stores and appends data of a search pattern to an already existing local variable and list them numerically as standard out 'STDOUT'.
Will the Python code below print something? And will it terminate?
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
a. no and no
b. yes and no
c. no and yes
d. yes and yes
e. syntax error
Answer:
Yes and Yes
Explanation:
When programs are written without indentation; it becomes a problem to read;
I'll rewrite your program as follows:
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
Using the above as a point of reference,
Yes, the program will run and Yes, it'll terminate;
Because n is initialized to 3 at line 6 (where the main starts);
The following is passed to the function; s = "hi" and n=3
This prints "hi", three times
s = "there" and n=3 is then passed to the function print_n, afterwards;
The function then prints "there" three times
Then, the program terminates
Does the cloud solution offer equal or greater data security capabilities than those pro-vided by your organization’s data center?
Answer:I think greater. Answer my question that I posted plz
Explanation:
#Write a function called population_density. The function #should take one parameter, which will be a list of #dictionaries. Each dictionary in the list will have three #key-value pairs: # # - name: the name of the country # - population: the population of that country # - area: the area of that country (in km^2) # #Your function should return the population density of all #the countries put together. You can calculate this by #summing all the populations, summing all the areas, and #dividing the total population by the total area. # #Note that the input to this function will look quite long; #don't let that scare you. That's just because dictionaries #take a lot of text to define. #Add your function here!
Answer:
def population_density(dictionary_list):
""" this function calculates the population density of a list of countries"""
total_population= 0
total_area= 0
for country in dictionary_list:
total_population += country['population']
total_area += country['area']
population_density = total_population / total_area
return population_density
Explanation:
In python, functions are defined by the "def" keyword and a dictionary is used to hold immutable data key and its value. The for loop is used to loop through the list of dictionaries and the values of the country data and extracted with bracket notation.
(Process scores in a text file) Suppose that a text file contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks. Your program should prompt the user to enter a filename. Here is a sample run:
Answer:
Here is the Python program:
def scores(file): # method scores that takes a file name as parameter and returns the sum and average of scores in a file
with open(file, 'r') as infile: # open the file in read mode
lines = [score.split() for score in infile] # split the scores into a list
print("The scores are:",lines) #print the scores
for line in lines: # loops through each score
total= sum(int(score) for score in line) # adds the scores
average =total/len(line) # computes average by taking sum of scores and dividing by number of scores in file
print("The sum is:", total) #prints the sum of scores
print("The average is:", "{:.2f}".format(average)) #prints the average
filename = input("Enter name of the file: ") #prompts user to enter name of file
scores(filename) #calls scores method by passing the file name to it in order to compute sum and average of file contents i.e. scores
Explanation:
It is assumed that the scores in the file are separated by a blank space.
The scores() method takes a file name as parameter. Then it opens that input file in read mode using object infile.
split() method is used to split the scores in a file into a list. Suppose the scores are 1 2 3 4 5 6 . So after the split, they become ['1', '2', '3', '4', '5', '6']
The loop iterates through each score in the file, splits them into a list and stores this list in lines. The next print statement prints these scores in a list.
The second loop for line in lines iterates through each score of the list and the statements: total= sum(int(score) for score in line) and average =total/len(line) computes the total and average of scores.
total= sum(int(score) for score in line) statement works as follows:
for loop iterates through each element of list i.e. each score
int() converts that string element into integer.
sum() method adds the integers to compute their total.
So if we have ['1', '2', '3', '4', '5', '6'] each element i.e. 1,2,3,4,5,6 is converted to integer by int() and then added together by sum method. So this becomes 1+2+3+4+5+6 = 21. This result is stored in total. Hence
total = 21.
average = total/len(line) works as follows:
The computed sum of scores stored in total is divided by the number of scores. The number of scores is computed by using len() method which returns the length of the line list. So len() returns 6. Hence
average = total/len(line)
= 21 / 6
average = 3.5
The next two print statement prints the value of sum and average and "{:.2f}".format(average)) prints the value of average up to 2 decimal places.

Explain data hazard and structural hazard. Then, explain how we can prevent each type of hazard. Provide two examples to support your explanations
Answer:
Answered below
Explanation:
Data hazards happen when instructions exhibiting data dependence modify data in the different stages of a pipeline. Potential data hazards when not attended to, can result in race hazards or race conditions. Examples of situations where data hazards can occur is read after write, write after read, write after write. To resolve data hazards we can insert a pipeline whenever a read after write, dependence is encountered, use out-of-order execution or use operand forwarding.
Structural hazards happen when multiple instructions which are already in pipeline new the same resource. Example is a situation which many instructions are ready to execute an there is a single Arithmetic Logic Unit. Methods for preventing this hazard include pipeline break an pipeline flushing.
In what way does a hash provide a better message integrity check than a checksum (such as the Internet checksum)?
Answer:
Hash function have less collision than a internet checksum because of computational infeasibility.
Explanation:
A collision means there is more then one way to produce the same sum. It is nearly difficult to developed two messages with same hash however, in checksum, it is more easier to develop or modify two messages to have same sum, thereby enabling attackers to have access to the message or the information arising to less message integrity.
Complete the function to replace any period by an exclamation point. Ex: "Hello. I'm Miley. Nice to meet you." becomes:
"Hello! I'm Miley! Nice to meet you!"
#include
#include
using namespace std;
void MakeSentenceExcited(char* sentenceText) {
/* Your solution goes here */
}
int main() {
const int TEST_STR_SIZE = 50;
char testStr[TEST_STR_SIZE];
strcpy(testStr, "Hello. I'm Miley. Nice to meet you.");
MakeSentenceExcited(testStr);
cout << testStr << endl;
return 0;
}
Answer:
Here is the complete function:
void MakeSentenceExcited(char* sentenceText) { // function that takes the text as parameter and replaces any period by an exclamation point in that text
int size = strlen(sentenceText); //returns the length of sentenceText string and assigns it to size variable
char * ptr; // character type pointer ptr
ptr = sentenceText; // ptr points to the sentenceText string
for (int i=0; i<size; i++){ //iterates through the sentenceText string using i as an index
if (sentenceText[i]=='.'){ // if the character at i-th index of sentenceText is a period
sentenceText[i]='!'; } } } //places exclamation mark when it finds a period at i-th index of sentenceText
Explanation:
The program works as follows:
Suppose we have the string:
sentenceText = "Hello. I'm Miley. Nice to meet you."
The MakeSentenceExcited method takes this sentenceText as parameter
int size = strlen(sentenceText) this returns the length of sentenceText
The size of sentenceText is 35 as this string contains 35 characters
size = 35
Then a pointer ptr is declared which is set to point to sentenceText
for (int i=0; i<size; i++) loop works as follows:
1st iteration:
i=0
i<size is true because i=0 and size = 35 so 0<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[0]=='.')
The first element of sentenceText is H
H is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 1
2nd iteration:
i=1
i<size is true because i=1 and size = 35 so 1<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[1]=='.')
This is the second element of sentenceText i.e. e
e is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 2
So at each iteration the if condition checks if the character at i-th index of string sentenceText is a period.
Now lets see a case where the element at i-th index is a period:
6th iteration:
i=5
i<size is true because i=5 and size = 35 so 5<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[5]=='.')
This is the character at 5th index of sentenceText i.e. "."
So the if condition evaluates to true and the statement inside if part executes:
sentenceText[i]='!'; statement becomes:
sentenceText[5]='!'; this means that the character at 5th position of sentenceText string is assigned an exclamation mark.
So from above 6 iterations the result is:
Hello!
This loop continues to execute until all the characters of sentenceText are checked and when the value of i gets greater than or equal to the length of sentenceText then the loop breaks.

Your task is to write and test a function which takes one argument (a year) and returns True if the year is a leap year, or False otherwise. The seed of the function is already sown in the skeleton code in the editor. Note: we've also prepared a short testing code, which you can use to test your function. The code uses two lists - one with the test data, and the other containing the expected results. The code will tell you if any of your results are invalid.
Answer:
function isLeapYear( aYear ){
var confirmYear= year % 400 === 0 || (year % 100 !== 0 && year % 4 === 0);
return confirmYear ? True : False;
}
Explanation:
The javascript function above requires an argument which is the year when it is passed, it is analyzed, counting the number of days in that year and a boolean value of true or false is dynamically assigned to the variable 'confirmYear'.
The ternary operator would logically select the right value, which is outputted to the user. To test the function, use the console to call the function with an argument.
console.log( isLeapYear( 1999 ) );

Reasons why operating system is pivotal in teaching and learning
Answer:
Explanation: The operating system simply acts as the communication interface between the user and the components if a computer including it's hardware. The reasons why an operating system is pivotal in leaching and learning includes :
In most cases, teaching and learning requires the use of application programs or softwares which could be the program to be learnt or that which is used to aid learning. Irrespective of the type of application program, it's installation and usage depends and is made possible with the help of an operating system. Programs used for video sessions during teaching, writing programs and document editors all require an operating system in other to aid installation and ultimately function.
Define the missing method. licenseNum is created as: (100000 * customID) licenseYear, where customID is a method parameter. Sample output with inputs 2014 777:
Answer:
I am writing the program in JAVA and C++
JAVA:
public int createLicenseNum(int customID){ //class that takes the customID as parameter and creates and returns the licenseNum
licenseNum = (100000 * customID) + licenseYear; //licenseNum creation formula
return(licenseNum); }
In C++ :
void DogLicense::CreateLicenseNum(int customID){ //class that takes the customID as parameter and creates the licenseNum
licenseNum = (100000 * customID) + licenseYear; } //licenseNum creation formula
Explanation:
createLicenseNum method takes customID as its parameter. The formula inside the function is:
licenseNum = (100000 * customID) + licenseYear;
This multiplies 100000 to the customID and adds the result to the licenseYear and assigns the result of this whole expression to licenseNum.
For example if the SetYear(2014) means the value of licenseYear is set to 2014 and CreateLicenseNum(777) this statement calls createLicenseNum method by passing 777 value as customID to this function. So this means licenseYear = 2014 and customID = 777
When the CreateLicenseNum function is invoked it computes and returns the value of licenseNum as:
licenseNum = (100000 * customID) + licenseYear;
= (100000 * 777) + 2014
= 77700000 + 2014
licenseNum = 77702014
So the output is:
Dog license: 77702014
To call this function in JAVA:
public class CallDogLicense {
public static void main(String[] args) {//start of main() function
DogLicense dog1 = new DogLicense();//create instance of Dog class
dog1.setYear(2014); // calls setYear passing 2014
dog1.createLicenseNum(777);// calls createLicenseNum passing 777 as customID value
System.out.println("Dog license: " + dog1.getLicenseNum()); //calls getLicenseNum to get the computed licenceNum value
return; } }
Both the programs along with the output are attached as a screenshot.
Answer:
public int createLicenseNum(int customID){
licenseNum = (100000 * customID) + licenseYear;
return(licenseNum);

Complete the function by filling in the missing parts. The color_translator function receives the name of a color, then prints its hexadecimal value. Currently, it only supports the three additive primary colors (red, green, blue), so it returns "unknown" for all other colors. m 1 - def color_translator(color): 2. if _== "red": 3 hex_color = "#ff0000" 4- elif == "green": 5 hex_color = "#00ff00" elif == "blue": hex_color = "#0000ff" in 0 hex_color = "unknown" return _ . 12 13 14 15 16 17 print(color_translator("blue")) # Should be #0000ff print(color_translator ("yellow")) # should be unknown print(color_translator("red")) # Should be #ff0000 print(color_translator ("black")) # should be unknown print(color_translator("green")) # Should be #00ff00 print(color translator("")) # should be unknown Run Reset
Answer:
The completed program is
def color_translator(color):
if color == "red":
hex_color = "#ff0000"
elif color == "green":
hex_color = "#00ff00"
elif color == "blue":
hex_color = "#0000ff"
else:
hex_color = "unknown"
return hex_color
Explanation:
Since the parameter in the above function is color,
This variable will serve as the name of a color and it'll be used in the conditional statements to check if the name of color is any of red, green and blue;
And that is why we have
if color == "red":
elif color == "green":
elif color == "blue":
The variable used to hold the color codes, hex_color, will be returned at the end of the function and that's why we have
return hex_color
When the program is tested with print(color_translator("blue")) and others, it prints the desired output
Assign decoded_tweet with user_tweet, replacing any occurrence of 'TTYL' with 'talk to you later'.Sample output with input: 'Gotta go. I will TTYL.'Gotta go. I will talk to you later.code given:user_tweet = input()decoded_tweet = ''' Your solution goes here '''print(decoded_tweet)
Answer:
Here is the Python program:
user_tweet = input()
decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')
print(decoded_tweet)
Explanation:
The program works as follows:
Suppose the input is: 'Gotta go. I will TTYL'
This is stored in user_tweet. So
user_tweet = 'Gotta go. I will TTYL'
The statement: user_tweet.replace('TTYL', 'talk to you later') uses replace() method which is used to replace a specified string i.e. TTYL with another specified string i.e. talk to you later in the string stored in user_tweet.
The first argument of this method replace() is the string or phrase that is to be replaced and the second argument is the string or phrase that is to replace that specified string in first argument.
So this new string is assigned to decoded_tweet, after replacing 'TTYL' with 'talk to you later' in user_tweet.
So the print statement print(decoded_tweet) displays that new string.
Hence the output is:
Gotta go. I will talk to you later.
#Write a function called fancy_find. fancy_find should have #two parameters: search_within and search_for. # #fancy_find should check if search_for is found within the #string search_within. If it is, it should print the message #"[search_for] found at index [index]!", with [search_for] #and [index] replaced by the value of search_for and the #index at which it is found. If search_for is not found #within search_within, it should print, "[search_for] was #not found within [search_within]!", again with the values #of search_for and search_within. # #For example: # # fancy_find("ABCDEF", "DEF") -> "DEF found at index 3!" # fancy_find("ABCDEF", "GHI") -> "GHI was not found within ABCDEF!"
Answer:
Here is the Python program:
def fancy_find(search_within , search_for): # function definition of fancy_find function that takes two parameters
index = 0 #to store the index of search_within where the search_for string is found
if search_for in search_within: #checks if the string search_for is present in string search_within
sf = search_for[0] #points to the first character of the search_for
for sw in search_within: #iterates through search_within
if sw == sf: #if the first character of search_for is equal to the character at sw index of search_within
if search_within[index:index+len(search_for)] == search_for: #checks if the value of search_for is found in search_within
print(search_for,"found at index",index,"!") #if above condition is true prints the message "[search_for] found at index [index]!", with [search_for] and [index] replaced by the value of search_for and the index at which it is found
return ""
index += 1 #increments value of index at each iteration
print(search_for,"is not found within", search_within) #if search_for is not found within search_within, prints message "[search_for] was not found within [search_within]!" with the values of search_for and search_within.
return ""
#following two statements are used to test the working of above function
print(fancy_find("ABCDEF", "DEF")) #calls fancy_find() passing "ABCDEF" as search_within and "DEF" as search_for
print(fancy_find("ABCDEF", "GHI")) #calls fancy_find() passing "ABCDEF" as search_within and "GHI" as search_for
Explanation:
The program is well explained in the comments. I will explain the working of the function with the help of an example:
Suppose
search_within = "ABCDEF"
search_for = "DEF"
We have to find if search_for i.e. DEF is present in search_within i.e. ABCDEF
if search_for in search_within statement checks using in operator that if DEF is included in ABCDEF. Here this condition evaluates to true so the next statement sf = search_for[0] executes which sets the first element of search_for i.e. D to sf. So sf = 'D'
for sw in search_within this statement has a for loop that iterates through ABCDEF and works as following:
At first iteration:
sw contains the first character of search_within i.e. A
if sw == sf: condition checks if the first character of the search_for i.e. D is equal to sw i.e. A. Its not true so the program control moves to this statement:
index += 1 This increases the value of index by 1. index was initialized to 0 so now it becomes 1. Hence index=1
At second iteration:
sw contains the second character of search_within i.e. B
if sw == sf: condition checks if the first character of the search_for i.e. D is equal to sw i.e. B Its not true so the program control moves to this statement:
index += 1 This increases the value of index by 1. index was initialized to 0 so now it becomes 2. Hence index=2
At third iteration:
sw contains the third character of search_within i.e. C
if sw == sf: condition checks if the first character of the search_for i.e. D is equal to sw i.e. C Its not true so the program control moves to this statement:
index += 1 This increases the value of index by 1. index was initialized to 0 so now it becomes 3. Hence index=3
At fourth iteration:
sw contains the third character of search_within i.e. D
if sw == sf: condition checks if the first character of the search_for i.e. D is equal to sw i.e. D. Its true so so the program control moves to this statement:
if search_within[index:index+len(search_for)] == search_for:
current value of index=3
len(search_for) returns the length of DEF i.e. 3
So the if condition checks for the search_for in search_within. The statement becomes:
if search_within[3:3+3] == search_for:
search_within[3:3+3] means from 3rd index position of search_within to 6-th index position of the search_within. This means from 4th element of search_within i.e. D to the last. Hence search_within[3:3+3] is equal to DEF.
search_for = DEF so
if search_within[3:3+3] == search_for: checks if
search_within[3:3+3] = DEF is equals to search_for = DEF
Yes it is true so
print(search_for,"found at index",index,"!") statement is executef which prints the following message:
DEF found at index 3!
This output is because search_for = "DEF" and index=3
Management wants to ensure any sensitive data on company-provided cell phones is isolated in a single location that can be remotely wiped if the phone is lost. Which of the following technologies BEST meets this need?a. Geofencingb. containerizationc. device encryptiond. Sandboxing
Answer:
B. Containerization.
Explanation:
In this scenario, management wants to ensure any sensitive data on company-provided cell phones is isolated in a single location that can be remotely wiped if the phone is lost. The technology which best meets this need is containerization.
In Computer science, containerization can be defined as a process through which software applications are used or operated in an isolated space (environment). It uses an operating system level virtualization method, such as a single host OS kernel, UFS, namespaces, Cgroups, to run software applications.
Hence, using the containerization technology makes it easy to wipe off the cell phones if lost because it is isolated in a single location.
