Write a function that takes in a sequence s and a function fn and returns a dictionary. The values of the dictionary are lists of elements from s. Each element e in a list should be constructed such that fn(e) is the same for all elements in that list. Finally, the key for each value should be fn(e)
def group_by(s, fn):
""" >>> group_by([12, 23, 14, 45], lambda p: p // 10)
{1: [12, 14], 2: [23], 4: [45]}
>>> group_by(range(-3, 4), lambda x: x * x)
{0: [0], 1: [-1, 1], 4: [-2, 2], 9: [-3, 3]}
"""

Answer:

The answer is "Option c".

Explanation:

It is an internal page reference which, whilst also completely new pages, allow navigating around the current page. They are largely used only for bypassing and 'skipping' across redundant web page content by voice command users, that's why the CJ would use a skip link to enable those users to bypass specific navigation, and he also wants to put this link on the right, but first, he needs to use the left property.

The output function is used to display the program's output.

Explanation:

As far as I know this must be the answer. As tge output devices such as Monitor and Speaker displays the output processed.

The display function is used to display the program's output. The correct option is C.

Display Function Usage displays a list of function identifiers. It can also be used to display detailed usage information about a specific function, such as a list of user profiles with the function's specific usage information.

The displayed values include the prefix, measuring unit, and required decimal places.

Push buttons can be used to select functions such as summation, minimum and maximum value output, and tare. A variety of user inputs are available.

A display is a device that displays visual information. The primary goal of any display technology is to make information sharing easier. The display function is used to display the output of the program.

Thus, the correct option is C.

Answer:

To create a public key signature, you would use the _private_ key.

Explanation:

To create a public key signature, a  private key is essential to enable authorization.

A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.

The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.

The public key uses different keys to make data readable and unreadable.

The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

Shortest Remaining Time First, also popularly referred to by the acronym SRTF, is a type of scheduling algorithm, used in operating systems. Other times it's not called by its name nor its acronym, it is called the preemptive version of SJF scheduling algorithm. The SJF scheduling algorithm is another type of scheduling algorithm.

The Shortest Remaining Time First has been touted by many to be faster than the SJF

The answer to the question which asks if the Shortest Remaining Time First is the best preemptive scheduling algorithm that can be implemented in an Operating System is:

This refers to the type of scheduling algorithm which is used to schedule tasks that would be executed in the processing unit in an Operating System based on the shortest time taken to execute the task.

With this in mind, we can see that this is the best preemptive scheduling algorithm that can be implemented in an Operating System because it makes task execution faster.

var f = new BigNumber("1");

for (let i=1; i <= 100; i++) {

 f = f.times(i);

 console.log(`${i}! = ${f.toFixed()}`);

}

Above is a solution in javascript. You will need a bignumber library to display the numbers in full precision.

Answer:

public class Main

{

public static void main(String[] args) {

 System.out.println(min(3, -2, 7));

}

public static int min(int n1, int n2, int n3){

    int smallest = Math.min(Math.min(n1, n2), n3);

    return smallest;

}

}

Explanation:

*The code is in Java.

Create a method named min that takes three parameters, n1, n2, and n3

Inside the method:

Call the method Math.min() to find the smallest among n1 and n2. Then, pass the result of this method to Math.min() again with n3 to find the min among three of them and return it. Note that Math.min() returns the smallest number among two parameters.

In the main:

Call the method with parameters given in the example and print the result

Methods are named program statements that are executed when called/invoked.

The method in Python, where comments are used to explain each line is as follows:

#This defines the method

def mmin(a,b,c):

   #This calculates the smallest of the three values using math.min

   minNum = min(a,b,c)

   #This prints the smallest value

   return minNum

Answer: (A) pause or stop while reading.

Explanation:

Answer:

D. all of the above

Explanation:

A option is correct and function definition must be written before they are called by another part of your program. But in languages such as C++ you can write the prototype of the function before it is called anywhere in the program and later write the complete function implementation. I will give an example in Python:

def addition(a,b): #this is the definition of function addition

    c = a + b

    return c    

print(addition(1,3)) #this is where the function is called

B option is correct and function definition must declare a name for the function. If you see the above given function, its name is declared as addition

C option is correct and function definition must include information regarding any arguments (if any) that will be passed to the function. In the above given example the arguments are a and b. If we define the above function in C++ it becomes: int addition( int a, int b)

This gives information that the two variables a and b that are parameters of the function addition are of type int so they can hold integer values only.

Hence option D is the correct answer. All of the above options are correct.

Written in Python

names = []

times = []

     times.append(time)

if times[2]>=times[1] and times[2]>=times[0]:

     print(names[2]+" "+times[2])

     if times[1]>=times[0]:

           print(names[1]+" "+times[1])

           print(names[0]+" "+times[0])

   else:

I've added the full source code as an attachment where I used comments to explain difficult lines

Answer:

Here is the corrected program:

import java.util.Scanner; //to accept input from user

public class 02_14_Activity_one { //class name

    public static void main(String[] args) { //start of main method

    Scanner scan = new Scanner(System.in); //creates Scanner class object

  System.out.println("Enter first string"); //prompts user to enter first string

          String s1 = scan.nextLine(); //reads input string from user

  System.out.println("Enter second string"); //prompts user to enter second string

          String s2 = scan.nextLine(); //reads second input string from user

    System.out.println("Enter number of letters from each word"); //enter n

          int n = scan.nextInt(); //reads value of integer n from user

          System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

         } } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.

Explanation:

The errors were:

1.

Scanner scan = Scanner(System.in);

Here new keyword is missing to create object scan of Scanner class.

Corrected statement:

 Scanner scan = new Scanner(System.in);

2.

String s1 = nextLine();  

Here object scan is missing to call nextLine() method of class Scanner

Corrected statement:

String s1 = scan.nextLine();

3.

String s2 = Scanner.nextLine();

Here class is used instead of its object scan to access the method nextLine

Corrected statement:

String s2 = scan.nextLine();

4.

String n = scan.nextLine();

Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value

Corrected statement:

int n = scan.nextInt();

5.

System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));

This statement is also not correct

Corrected statement:

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

This works as follows:

s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.

s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.
