Write an expression that evaluates to True if the string associated with s1 is greater than the string associated with s2
Answers
Answer:
Explanation:
The following code is written in Python. It is a function that takes two string parameters and compares the lengths of both strings. If the string in variable s1 is greater then the function returns True, otherwise the function returns False. A test case has been provided and the output can be seen in the attached image below.
def compareStrings(s1, s2):
if len(s1) > len(s2):
return True
else:
return False
print(compareStrings("Brainly", "Competition"))

It is common for people to name directories as dir1, dir2, and so on. When there are ten or more directories, the operating system displays them in dictionary order, as dir1, dir10, dir11, dir12, dir2, dir3, and so on. That is irritating, and it is easy to fix. Provide a comparator that compares strings that end in digit sequences in a way that makes sense to a human. First compare the part before the digit as strings, and then compare the numeric values of the digits.

Here the code is given as follows,
Explanation:
Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i
Answers
Answer:
The function is as follows:
int returnsFixed(int arr [],int n){
int retVal = -1;
for(int i = 0; i<n;i++){
if(i == arr[i]){
retVal = i;
break;
}
}
return retVal;
}
Explanation:
This defines the functionl it receives the array and the length of the array
int returnsFixed(int arr [],int n){
This initializes the return value to -1
int retVal = -1;
This iterates through the array
for(int i = 0; i<n;i++){
This checks if i equals arr[i]
if(i == arr[i]){
If yes, the return value (i.e. the fixed point) is set to i
retVal = i;
And the code is exited
break;
} This ends the if condition
} This ends the iteration
This returns the calculated fixed point
return retVal;
}

Which attack form either exploits a software flaw or floods a system with traffic in order to prevent legitimate activities or transactions from occurring?
Answers
Answer:
Denial of service attack.
Explanation:
In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, sniffing, DOS attack, etc.
A denial of service (DOS) attack is a form of cyber attack that involves either the exploitation of a software flaw or overwhelmingly floods a computer system in a network with traffic in order to prevent authorized users from performing legitimate activities or transactions.
Some of the ways to prevent vulnerability or cyber attacks in a network are;
1. Ensure you use a very strong password with complexity through the use of alphanumerics.
2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.

Which of the following restricts the ability for individuals to reveal information present in some part of the database?
a. Access Control
b. Inference Control
c. Flow Control
d. Encyption
Answers
Answer:
it would have to be flow control which would be C.
Explanation:
Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.
What is Flow Control?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.
A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.
The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.
Thus, option C is correct.

In the forward chaining technique, used by the inference engine component of an expert system, the _____ condition is evaluated first.
Answers
Answer:
"if" is the right response.
Explanation:
Forward chaining is being utilized just to split the logical sequential order down as well as operate throughout every component once the preceding one is accomplished, from start to finish.Its whole algorithm begins with proven information that activates all the rules, which are fulfilled as well as makes established realities even more complete.A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?
Answers
Answer:
Hence the answer is given as follows,
Explanation:
Base Case:-
If (num == 0) //This is the base case for the given recursive method
return 1;
If(num % 2!=0) checks whether num is odd.
The above condition is true for all odd numbers and false for even numbers.
if the remainder is not equal to zero when we divide the number with 2 then it is odd.
The method:-
The above recursive method calculates the product of odd numbers up to the given range(that is num)
For num=5 => 15(5*3*1).
For num=7 => 105(7*5*3*1).
For num=10 => 945(9*7*5*3*1).

I have a list of happiness and six explanatory vars.
exp_vars = ['Happiness', 'LogGDP', 'Support', 'Life', 'Freedom', 'Generosity', 'Corruption']
1. Define a variable called explanatory_vars that contains the list of the 6 key explanatory variables
2. Define a variable called plot_vars that contains Happiness and each of the explanatory variables. (Hint: recall that you can concatenate Python lists using the addition (+) operator.)
3. Using sns.pairplot, make a pairwise scatterplot for the WHR data frame over the variables of interest, namely the plot_vars. To add additional information, set the hue option to reflect the year of each data point, so that trends over time might become apparent. It will also be useful to include the options dropna=True and palette='Blues'.

Explanation:The function strpos() is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.

Write a programmer defined function that compares the ASCII sum of two strings. To compute the ASCII sum, you need to compute the ASCII value of each character of the string and sum them up. You will thus need to calculate two sums, one for each string. Then, return true if the first string has a larger ASCII sum compared to the second string, otherwise return false. In your main function, prompt the user to enter two strings with a suitable message and provide the strings to the function during function call. The user may enter multiple words for either string. Then, use the Boolean data returned by the function to inform which string has the higher ASCII sum.
Answers
Answer:
The program in Python is as follows:
def ASCIIsum(str1,str2):
asciisum1 = 0; asciisum2 = 0
for chr in str1:
asciisum1 += (ord(chr) - 96)
for chr in str2:
asciisum2 += (ord(chr) - 96)
if asciisum1 > asciisum2:
return True
else:
return False
str1 = input("Enter first string: ")
str2 = input("Enter second string: ")
if ASCIIsum(str1,str2) == True:
print(str1,"has a higher ASCII value")
else:
print(str2,"has a higher ASCII value")
Explanation:
This defines the function
def ASCIIsum(str1,str2):
This initializes the ascii sum of both strings to 0
asciisum1 = 0; asciisum2 = 0
This iterates through the characters of str1 and add up the ascii values of each character
for chr in str1:
asciisum1 += (ord(chr) - 96)
This iterates through the characters of str2 and add up the ascii values of each character
for chr in str2:
asciisum2 += (ord(chr) - 96)
This returns true if the first string has a greater ascii value
if asciisum1 > asciisum2:
return True
This returns false if the second string has a greater ascii value
else:
return False
The main begins here
This gets input for first string
str1 = input("Enter first string: ")
This gets input for second string
str2 = input("Enter second string: ")
If the returned value is True
if ASCIIsum(str1,str2) == True:
Then str1 has a greater ascii value
print(str1,"has a higher ASCII value")
If otherwise
else:
Then str2 has a greater ascii value
print(str2,"has a higher ASCII value")

It creates a sum variable which holds the sum of all the values in the array and the count variable which holds the number of elements in the array. Then it uses a For Each loop to loop through the array and go adding each element to the sum variable. Finally it calculates the average by dividing the sum by the variable count and returns the average to the user. A test case has been created in the main method using the example in the question. The output can be seen in the image attached below.

double sum = 0;
double count = myArr.length;
for (int x: myArr) {
sum += x;
}
double average = sum / count;

3) If number is zero, number is displayed;
Explanation:
The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement. Therefore, the only statement in the question that is actually true would be ...
3) If number is zero, number is displayed;
Answer:
If number is zero, number is displayed
Explanation:
Given
The above code segment
Required
What is true about the code segment
Analyzing the options, we have:
(1) Wrong statement because there is no else clause
The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program
Hence, (1) is false
(2) The print statement must be in { }
There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.
Hence, (2) is false
(3) number is displayed, if input is 0
In the analysis of the program, we have: number <=0
i.e. the if statement is true for only inputs less than 0 or 0.
Hence, number will be printed and (3) is false
(4) number is displayed for positive inputs
The valid inputs have been explained in (3) above;
Hence, (4) is false.
(5) is also false

Answers
Answer:
Explanation:
Marketing your product directly over the internet can lead to much greater profits and there are many options that you can choose from in order to target the correct audience. Unfortunately, doing so does require marketing knowledge and is basically like growing a business. If you were to use intermediaries they already have the knowledge necessary to market your product but will take a percentage of the profits, which will ultimately limit your gains. Since Gray London is a race car driver, I am assumming that he does not have any prior technological expertise or marketing expertise, therefore I would recommend using intermediaries.
SQLite is a database that comes with Android. Which statements is/are correct?
The content of an SQLite database is stored in XML formatted files because XML is the only file format supported by Android OS.
A SQLite database is just another name for a Content Provider. There is no difference as the SQLite implementation implements the Content Provider interface.
If an app creates an SQLite database and stores data in it, then all of the data in that particular database will be stored in one, single file.
A database query to an SQLite database usually returns a set of answers
To access individual entries, SQLite provides a so-called Cursor to enumerate all entries in the set.
This is yet another example of the Iterator pattern.
Answers
Answer:
1. Wrong as per my knowledge, SQLite may be an electronic database software that stores data in relations(tables).
2. Wrong. Content provider interface controls the flow of knowledge from your android application to an external data storage location. Data storage is often in any database or maybe it'll be possible to store the info in an SQLite database also.
3.Right. SQLite uses one file to store data. It also creates a rollback file to backup the stored data/logs the transactions.
4. Wrong. The queries are almost like a traditional electronic database system, the queries are going to be answered as per the conditions given and should return a group of answers or one answer depending upon the info and sort of query used.
5. Right. A cursor helps to point to one entry within the database table. this may be very helpful in manipulating the present row of the query easily.

Write a removeDuplicates() method for the LinkedList class we saw in lecture. The method will remove all duplicate elements from the LinkedList by removing the second and subsequent elements. If there is only one copy of an element, it is not removed. The list size should shrink accordingly based on the number of duplicates removed.
Answers
Answer:
removeDuplicates() function:-
//removeDuplicates() function removes duplicate elements form linked list.
void removeDuplicates() {
//declare 3 ListNode pointers ptr1,ptr2 and duplicate.
//initially, all points to null.
ListNode ptr1 = null, ptr2 = null, duplicate = null;
//make ptr1 equals to head.
ptr1 = head;
//run while loop till ptr1 points to second last node.
//pick elements one by one..
while (ptr1 != null && ptr1.next != null)
{
// make ptr2 equals to ptr1.
//or make ptr2 points to same node as ptr1.
ptr2 = ptr1;
//run second while loop to compare all elements with above selected element(ptr1->val).
while (ptr2.next != null)
{
//if element pointed by ptr1 is same as element pointed by ptr2.next.
//Then, we have found duplicate element.
//Now , we have to remove this duplicate element.
if (ptr1.val == ptr2.next.val)
{
//make duplicate pointer points to node where ptr2.next points(duplicate node).
duplicate = ptr2.next;
//change links to remove duplicate node from linked list.
//make ptr2.next points to duplicate.next.
ptr2.next = duplicate.next;
}
//if element pointed by ptr1 is different from element pointed by ptr2.next.
//then it is not duplicate element.
//So, move ptr2 = ptr2.next.
else
{
ptr2 = ptr2.next;
}
}
//move ptr1 = ptr1.next, after check duplicate elements for first node.
//Now, we check duplicacy for second node and so on.

#include
using namespace std;
class PersonData {
public:
void SetName(string userName) {
lastName = userName;
};
void SetAge(int numYears) {
ageYears = numYears;
};
// Other parts omitted
void PrintAll() {
cout << "Name: " << lastName;
cout << ", Age: " << ageYears;
};
private:
int ageYears;
string lastName;
};
class StudentData: public PersonData {
public:
void SetID(int studentId) {
idNum = studentId;
};
int GetID() {
return idNum;
};
private:
int idNum;
};
int main() {
StudentData courseStudent;
/* Your solution goes here */
return 0;
}
Answers
Answer:
Replace /* Your solution goes here */
with the following:
courseStudent.SetName("Smith");
courseStudent.SetAge(20);
courseStudent.SetID(9999);
courseStudent.PrintAll();
cout <<courseStudent.GetID();
Explanation:
From the given code segment, we have the following methods defined under the StudentData class;
SetName -> It receives name from the main
SetAge -> It receives age from the main
SetID --> It receives ID from the main and passes it to GetID method
printID --> Prints all the required output.
So, we have:
Pass name to setName
courseStudent.SetName("Smith");
Pass age to setAge
courseStudent.SetAge(20);
Pass ID to setID
courseStudent.SetID(9999);
Print all necessary outputs
courseStudent.PrintAll();
Manually print the student ID
cout <<courseStudent.GetID();
Functions IN C LANGUAGE
Problem 1
Function floor may be used to round a number to a specific decimal place. The statement
y = floor( x * 10 + .5 ) / 10;
rounds x to the tenths position (the first position to the right of the decimal point). The
statement
y = floor( x * 100 + .5 ) / 100;
rounds x to the hundredths position (the second position to the right of the decimal
point).
Write a program that defines four functions to round a number x in various ways
a. roundToInteger( number )
b. roundToTenths( number )
c. roundToHundreths( number )
d. roundToThousandths( number )
For each value read, your program should print the original value, the number rounded to
the nearest integer, the number rounded to the nearest tenth, the number rounded to
the nearest hundredth, and the number rounded to the nearest thousandth.
Input Format

Create and configure databases in oracle database management system operation administration
Answers
Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.
Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect. Submit the code of the program and your comments on the execution of the program.

Answer:
Following are the code to the given question:
import java.util.concurrent.*; //import package
public class Threads //defining a class Threads
{
private Integer s = new Integer(0);//defining Integer class object
public synchronized static void main(String[] args)//defining main method
{
Threads t = new Threads();//defining threads class object
System.out.println("What is sum ?" + t.s);//print value with message
}
Threads()//defining default constructor
{
ExecutorService exe = Executors.newFixedThreadPool(1000);//defining ExecutorService class object
System.out.println("With SYNCHRONIZATION........");//print message
for(int i = 1; i <= 1000; i++)//defining a for loop

exe.execute(new SumTask2());//calling execute method
System.out.println("At Thread " + i +" Sum= " + s + " , ");//print message with value
}
exe.shutdown();//calling shutdown method
while(!exe.isTerminated())//defining while loop that calls isTerminated method

public synchronized void run()//defining method run
{
int value = s.intValue() + 1;//defining variable value that calls intvalue which is increment by 1
s = new Integer(value);//use s to hold value
}
}
}
Output:
Please find the attached file.
Explanation:
In this code, a Threads class is defined in which an integer class object and the main method is declared that creates the Threads class object and calls its values.
Outside the method, the default constructor is declared that creates the "ExecutorService" and prints its message, and use a for loop that calls execute method which prints its value with the message.
In the class, a while loop is declared that calls "isTerminated" method, and outside the class "SumTask2" that inherits Runnable class and defined the run method and define a variable "value" that calls "intvalue" method which is increment by 1 and define s variable that holds method value.
