Explanation:
A password is a word that permit you to register, log or sign in a site.
Consider the following declaration:
String s = "cat";
Which of the following statements assigns the number of characters in s to k?
A. int k = s.length;
B. int k = s.length();
C. int k = s.size;
D. int k = s.size();
Consider the following declarations:
String s1 = "apple";
String s2 = "apple";
What is the result of s1.compareTo(s2)?
A. true
B. false
C. 0
D. 1
Consider the following declarations:
String s1 = "apple";
String s2 = "APPLE";
Which of the following expressions is true?
A. s1.equals(s2) && s1.equalsIgnoreCase(s2)
B. !s1.equals(s2) && s1.equalsIgnoreCase(s2)
C. s1.equals(s2) && !s1.equalsIgnoreCase(s2)
D. !s1.equals(s2) && !s1.equalsIgnoreCase(s2)
Answer:
B, C, B
Explanation:
According to my understanding of these questions, these are in Java.
For the first one, there is a built in function called .length() for a string, so it's answer B.
For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.
The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.

how to count binary ? Help Better understand this question
Explanation:
For each row in the picture, you have to switch on some of the bits to create the number on the left.
Each bit has a value, a "weight" so to speak. By switching on the bit, you add that weight to the sum.
These "weights" are shown at the top row.
So to create 4, it's easy, you just switch on the '4' bit.
Same for 128, only one bit has to be switched on.
40 is a bit more involved, now you have to switch on 32 and 8, since 32+8 is 40.
For every number, there is exactly one combination of switched on bits to create that number. In the case of 40, the binary representation is:
00101000.
write a short paragraph (three to four sentences) that explains how it works for computers and internet communications in relation to cybersecurity.
Answer:
Public and private keys form the basis for public key cryptography, also known as asymmetric cryptography. In public key cryptography, every public key corresponds to only one private key. Together, they are used to encrypt and decrypt messages. If you encode a message using a person’s public key, they can decode it using their matching private key.

Instructions
Make sure the file Multiply.py is selected and opened.
Write a counter-controlled while loop that uses the loop control variable (numberCounter) to take on the values 0 through 10.
In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop.

Answer:
That the mat will discolor and deteriorate
Explanation:
D
Yvonne will most likely worry that the mat will discolor and deteriorate. The correct option is D.
What is matting in photos?Matting is a decorative border that surrounds the artwork. It is typically built of mat board, a type of board designed specifically for this purpose. After cutting the mat board to size, one or more holes (entries) are cut in the mat board to act as windows for displaying art.
Matting is the technique of separating an image's foreground and background components. Typically, the photos are of a frame or a video file. It adds a decorative edge to the print and a mechanism for hanging the photo.
Matting involves using a front or window mat to separate the image from the frame's glass and to give an extra border around the photo.
Therefore, the correct option is D. that the mat will discolor and deteriorate.

Write a program that simulates applying a "boost" to a spaceship in a spaceship race game.
A spaceship makes progress by getting a "boost" value between 0 and 10. The boost value
is determined from generating a random number between 0 and 10. Assuming the starting
distance of the spaceship is 0, the program will output the boost value and the total
distance travelled by the spaceship after applying the boost. (Note: Two newlines are output
after the final output of the program).
When a random seed value of 2 is used, the output of the program will look like:
Boost: 6
Distance travelled: 6
Programming languages can be used to simulate several scenarios; in this case, the "boost"
The simulating program in C++ where comments are used to explain each line is as follows:
#include<iostream>
#include<cstdlib>
#include<ctime>
using namespace std;
int main() {
// This sets the seed to time(0)
srand(time(0));
// This generates a random number between 0 and 10, to represent the boost
int boost = rand()%10;
// This prints the required outputs
cout << "Boost: " << boost;
cout << "\nDistance travelled: " << boost;
return 0;
}

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.
Lists are used in Python to hold multiple values in one variable
(a) Nested list
A nested list is simply a list of list; i.e. a list that contains another list.
It is also called a 2 dimensional list.
An example is:
nested_list = [[ 1, 2, 3, 4] , [ 5, 6, 7]]
(b) The “*” operator
The "*" operator is used to calculate the product of numerical values.
An example is:
num1 = num2 * num3
List slices
This is used to get some parts of a list; it is done using the ":" sign
Take for instance, you want to get the elements from the 3rd to the 5th index of a list
An example is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
secondList = firstList[2:5]
The “+=” operator
This is used to add and assign values to variables
An example is:
num1 = 5
num2 = 3
num2 += num1
A list filter
This is used to return some elements of a list based on certain condition called filter.
An example that prints the even elements of a list is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
print(list(filter(lambda x: x % 2 == 0, firstList)))
A valid but wrong list operation
The following operation is to return a single list, but instead it returns as many lists as possible
def oneList(x, myList=[]):
myList.append(x)
print(myList)
oneList(3)
oneList(4)
