Cloud computing gives you the ability to expand and reduce resources according to your specific service requirement.
a. True
b. False
Answer:
a. True
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
In Computer science, one of the most essential characteristics or advantages of cloud computing is rapid elasticity.
By rapid elasticity, it simply means that cloud computing gives you the ability to expand and reduce resources according to your specific service requirement because resources such as servers can be used to execute a particular task and after completion, these resources can then be released or reduced.
Some of the examples of cloud computing are Google Slides, Google Drive, Dropbox, OneDrive etc.
CHALLENGE 7.1.1: Initialize a list. ACTIVITY Initialize the list short.names with strings 'Gus', Bob, and 'Ann'. Sample output for the given program Gus Bob Ann 1 short_names- Your solution goes here 2 # print names 4 print(short_names[0]) 5 print(short names [11) 6 print(short_names[2])
Answer:
short_names = ["Gus", "Bob", "Ann"]
print(short_names[0])
print(short_names[1])
print(short_names[2])
Explanation:
There are some typos in your code. In addition to the missing part of the code, I corrected the typos.
First of all, initialize the list called short_names. The list starts with "[" and ends with "]". Between those, there are must be the names (Since each name is a string, they must be written between "" and there must be a semicolon between each name)
Then, you can print each name by writing the name of the list and the index of the names between brackets (Index implies the position of the element and it starts with 0)
Write a program that asks the user to enter a series of numbers separated by commas. Here is an example of valid input: 7,9,10,2,18,6 The program should calculate and display the sum of all the numbers.
Answer:
Here is the JAVA program. Let me know if you need the program in some other programming language.
import java.util.Scanner; // used for taking input from user
public class Main{ //Main class
public static void main(String[] args) {//start of main() function body
Scanner scan = new Scanner(System.in); // creates a Scanner type object
String input; // stores input series
int sum = 0; //stores the sum of the series
System.out.println("Enter a series of numbers separated by commas: "); //prompts user to enter a series of numbers separated by comma
input = scan.nextLine(); //reads entire input series
String[] numbers = input.split("[, ]"); //breaks the input series based on delimiter i.e. comma and stores the split sub strings (numbers) into the numbers array
for (int i = 0; i < numbers.length; i++) { //loops through each element of numbers array until the length of the numbers reaches
sum += Integer.parseInt(numbers[i]); } // parses the each String element of numbers array as a signed decimal integer object and takes the sum of all the integer objects
System.out.println("Sum of all the numbers: " + sum); } } //displays the sum of all the numbers
Explanation:
The program prompts the user to enter a series separated by commas.
Then split() method is used to split or break the series of numbers which are in String form, into sub strings based on comma (,) . This means the series is split into separate numbers. These are stored in numbers[] array.
Next the for loop iterate through each sub string i.e. each number of the series, converts each String type decimal number to integer using Integer.parseInt and computes the sum of all these integers. The last print statement displays the sum of all numbers in series.
If the input is 7,9,10,2,18,6
Then the output is: 7+9+10+2+18+6
sum = 52
The program and its output is attached.

g Write a method that accepts a String object as an argument and displays its contents backward. For instance, if the string argument is "gravity" the method should display -"ytivarg". Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Answer:
The program written in C++ is as follows; (See Explanation Section for explanation)
#include <iostream>
using namespace std;
void revstring(string word)
{
string stringreverse = "";
for(int i = word.length() - 1; i>=0; i--)
{
stringreverse+=word[i];
}
cout<<stringreverse;
}
int main()
{
string user_input;
cout << "Enter a string: ";
getline (std::cin, user_input);
getstring(user_input);
return 0;
}
Explanation:
The method starts here
void getstring(string word)
{
This line initializes a string variable to an empty string
string stringreverse = "";
This iteration iterates through the character of the user input from the last to the first
for(int i = word.length() - 1; i>=0; i--) {
stringreverse+=word[i];
}
This line prints the reversed string
cout<<stringreverse;
}
The main method starts here
int main()
{
This line declares a string variable for user input
string user_input;
This line prompts the user for input
cout << "Enter a string: ";
This line gets user input
getline (std::cin, user_input);
This line passes the input string to the method
revstring(user_input);
return 0;

You are the network administrator for your company. A user reports that he cannot access network resources from his computer. He was able to access the resources yesterday. While troubleshooting his computer, you find that his computer is issued an Automatic Private IP Addressing (APIPA) address. All the network equipment in the user's computer is functioning properly because you are able to access the user's computer from a remote computer. What is most likely the problem
Answer:
the issued Automatic Private IP Addressing (APIPA) address.
Explanation:
Since we are told that the user was able to access the network resources yesterday, and all the network equipment in the user's computer is functioning properly, there is a very high possibility that because the user's computer has been issued an Automatic Private IP Addressing (APIPA) address, it affected his computer's ability to connect to a public network.
This is the case because private network IP addresses are known to prevent inflow and outflow of data onto public networks.

Answer:
Prediction
With regard to preparedness for hazard/disaster, technology such as AI are being explored to see how they can help to predict natural disaster.
If there is a breakthrough in this space, it will drastically reduce the negative impact of natural disasters such as floods and earthquakes as people will become ready to respond to them and mitigate their effects where possible.
In agriculture, there are factors which come together to bring about flooding. Flooding is one of the major disasters which cripples entire value chains. With a potential threat anticipated or predicted by AI, businesses can invest in technologies that can help protect the farms, farmland and other resources critical to such a supply chain.
AI-powered technologies that provide prediction services often combine this advanced computing prowess with the ability to process big data.
Technology can reach places that are unreachable by humans
AI-powered robots will soon become the norm.
Presently there are self-learning and self instructing robots powered by Artificial Intelligence that have applications in warfare, manufacturing, deepsea diving and intelligence gathering, and transportation. It is not out of place to predict that in the next decade, scientists would have perfected rescue robots that can go into very unstable terrain that have been damaged by flood or earthquake and attempt a rescue of lives and property at a scale that has never been possible before.
Connectivity
Connectivity helps people access to aid, resources that are critical for survival, transmission and receipt of life--saving information etc. CISCO has successfully used its technology called TacOps (short for Tactical Operations) successfully 45 times on over 5 continents.

Given an array of integers check if it is possible to partition the array into some number of subsequences of length k each, such that:
Each element in the array occurs in exactly one subsequence
For each subsequence, all numbers are distinct
Elements in the array having the same value must be in different subsequences
If it is possible to partition the array into subsequences while satisfying the above conditions, return "Yes", else return "No". A subsequence is formed by removing 0 or more elements from the array without changing the order of the elements that remain. For example, the subsequences of [1, 2, 3] are D. [1], [2], [3]. [1, 2], [2, 3], [1, 3], [1, 2, 3]
Example
k = 2.
numbers [1, 2, 3, 4]
The array can be partitioned with elements (1, 2) as the first subsequence, and elements [3, 4] as the next subsequence. Therefore return "Yes"
Example 2 k 3
numbers [1, 2, 2, 3]
There is no way to partition the array into subsequences such that all subsequences are of length 3 and each element in the array occurs in exactly one subsequence. Therefore return "No".

The readline method reads text until an end of line symbol is encountered, how is an end of line character represented
Answer:
\n
Explanation:
readline() method is used to read one line from a file. It returns that line from the file.
This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.
So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.
For example if the file "abc.txt" contains the lines:
Welcome to abc file.
This file is for demonstrating how read line works.
Consider the following code:
f = open("abc.txt", "r") #opens the file in read mode
print(f.readline()) # read one line from file and displays it
The output is:
Welcome to abc file.
The readline() method reads one line and the print method displays that line.
The fact that the speed of a vehicle is lower than the prescribed limits shall relieve the driver from the duty to decrease speed when approaching and crossing an intersection. True or false

Given the following code: public class Test { public static void main(String[] args) { Map map = new HashMap(); map.put("123", "John Smith"); map.put("111", "George Smith"); map.put("123", "Steve Yao"); map.put("222", "Steve Yao"); } } Which statement is correct?
Answer:
There are no statements in the question, so I explained the whole code.
Explanation:
A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.
For example, map.put("123", "John Smith"); -> key = 123, value = John Smith
Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.
Note that the key 222 also has Steve Yao for the value, that is totally acceptable.
Raj was concentrating so much while working on his project plan that he was late for a meeting. When he went back to his office, he noticed his system was restarted and his project file was not updated. What advice would you provide Raj in this situation?
Answer:
Explanation:
Depending on the software that Raj was using to create his project he should first see if the software itself saved the project. Usually many software such as those included in the Microsoft Office Suite save the file automatically every 5 minutes or so in case of a power outage or abrupt closure of the file. If this is not the case he should try and do a system restore with the unlikely hope that it restores an older version of his project.
In a situation like this, it would be advisable for Raj to contact IT personnels and seek if the files could be retrieved.
Raj being late for a meeting due to what he was doing meant that the project he was working on is very important. Therefore, to avoid losing thses files, he could contact the IT personnels and request if there is a way to retrieve the project file.These way, the files could be retrieved and avoid losing his work.

when an object is passed as a non-reference pointer parametor to a method, modifiying the members of that object from
Answer:
"this" keyword representing the class object itself.
Explanation:
Object-oriented programming concept emphasizes on using blueprints representing the structure of a data collection type to continuously create an instance of that data structure. The instance of that object is called a class object. It is used in database management systems to populate the database.
Functions defined in the class objects are called methods and are used specifically by the class instance to modify the data content of the class object defined.
When a member of a class is referenced in the class, it can be accessed with the "this" keyword. At an instance of the class object, the variable holding the object should be called to get the class content because of the "this" keyword binding the instance of the object to the method.
2- (8 point) Write a program using the instructions below. Assume that integers are stored in 4 bytes. a) Define an array of type int called apples with five elements, and initialize the elements to the even integers from 2 to 10. b) Define a pointer aPtr that points to a variable of type int. c) Print the elements of array values using a for statement. d) Write two separate statements that assign the starting address of the array to pointer variable aPtr. e) What physical address is aPtr pointing to? f) Print the elements of array values using pointer/offset notation. g) What address is referenced by aPtr + 3? What value is stored at that location? h) Assuming aPtr points to apples[4], what address is referenced by aPtr -= 4? What value is stored at that location?
Answer:
a)
int apples [5] = {2, 4, 6, 8, 10};
b)
int *aPtr //this is the pointer to int
Another way to attach a pointer to a an int variable that already exists:
int * aPtr;
int var;
aPtr = &var;
c)
for (int i = 0; i < size; i++){
cout << values[i] << endl; }
d)
aPtr = values;
aPtr = &values[0];
both the statements are equivalent
e)
If its referring to the part d) then the address is:
cout<<aPtr;
f)
for (int i = 0; i < size; ++i) {
cout<<*(vPtr + i)<<endl; }
g)
cout << (aPtr + 3) << endl; // address referenced by aPtr + 3
cout << *(aPtr + 3) << endl; // value stored at that location
This value stored at location is 8
h)
aPtr = &apples[4];
aPtr -= 4;
cout<<aPtr<<endl;
cout<<*aPtr<<endl;
Explanation:
a)
int apples [5] = {2, 4, 6, 8, 10};
In this statement the array names is apples, the size of the array is specified in square brackets. so the size is 5. The type of array apples is int this means it can store integer elements. The values or elements of the array apples are even integers from 2 to 10. So the elements of array are:
apples[0] = 2
apples[1] = 4
apples[2] = 6
apples[3] = 8
apples[4] = 10
b)
In this statement int *aPtr
The int* here is used to make the pointer aPtr points to integer object. Data type the pointer is pointing to is int. The asterisk symbol used with in makes this variable aPtr a pointer.
If there already exists an int type variable i.e. var and we want the pointer to point to that variable then declare an int type pointer aPtr and aPtr = &var; assigns the address of variable var to aPtr.
int * aPtr;
int var;
aPtr = &var;
c)
The complete program is:
int size= 5;
int values[size] = {2,4,6,8,10};
for (int i = 0; i < size; i++){
cout << values[i] << endl; }
The size of array is 5. The name of array is values. The elements of array are 2,4,6,8,10.
To print each element of the values array using array subscript notation, the variable i is initialized to 0, because array index starts at 0. The cout statement inside body of loop prints the element at 0-th index i.e. the first element of values array at first iteration. Then i is incremented by 1 each time the loop iterates, and this loop continues to execute until the value of i get greater of equal to the size i.e. 5 of values array.
The output is:
2
4
6
8
10
d)
aPtr = values;
This statement assigns the first element in values array to pointer aPtr. Here values is the address of the first element of the array.
aPtr = &values[0];
In this statement &values[0] is the starting address of the array values to which is assigned to aPtr. Note that the values[0] is the first element of the array values.
e)
Since &values[0] is the starting address of the array values to which is assigned to aPtr. So this address is the physical address of the starting of the array. If referring to the part d) then use this statement to print physical address is aPtr pointing to
cout<<aPtr;
This is basically the starting address of the array values to which is assigned to aPtr.
The output:
0x7fff697e1810
f)
i variable represents offset and corresponds directly to the array index.
name of the pointer i.e. vPtr references the array
So the statement (vPtr + i) means pointer vPtr that references to array values plus the offset i array index that is to be referenced. This statement gives the address of i-th element of values array. In order to get the value of the i-th element of values array, dereference operator * is used. It returns an ith value equivalent to the address the vPtr + i is pointing to. So the output is:
2
3
6
8
10
g)
values[0] is stored at 1002500
aPtr + 3 refers to values[3],
An integer is 4 bytes long,
So the address that is referenced by aPtr + 3 is
1002500 + 3 * 4 = 1002512
values[3] is basically the element of values array at 3rd index which is the 4th element of the array so the value stored at that referred location is 8.
h)
Given that aPtr points to apples[4], so the address stored in aPtr is
1002500 + 4 * 4 = 1002516
aPtr -= 4 is equivalent to aPtr = aPtr - 4
The above statement decrements aPtr by 4 elements of apples array, so the new value is:
1002516 - 4 * 4 = 1002500
This is the address of first element of apples array i.e 2.
Now
cout<<aPtr<<endl; statement prints the address referenced by aPtr -= 4 which is 1002500
cout<<*aPtr<<endl; statement prints the value is stored at that location which is 2.
