Levi wants to run 5 commands sequentially, but does not want to create a shell script. He knows that each command is going to ta

ke approximately 20 minutes to run individually. However, he would like to go to lunch 15 minutes from now. He knows that he can type all of the commands on the same line and separate them with a certain character to run them sequentially. Which character can he type after each command to have them run one after the next without requiring further input from him?

Levi can use the bash command to type all the commands on the same line to type one after the other character without requiring input.

<u>Explanation</u>:

  • He wants to run five commands. For one command it will take exactly 20 minutes. So it will take one hour forty minutes.
  • To type all of the commands on the same line Levi should use the bash command. For inserting the bash command Levi should use backslash \ as the last character of the line.

PilotLPTM [1.2K]

Answer:

Explanation:

Denote the five numbers as a, b, c, d and e.

The average is:

(a + b + c + d +e) ÷ 5.

Easily:

Learn how to do input and output operations in your programming language of choice.

Learn what average is (see Arithmetic mean - Wikipedia)

Learn how to code arithmetic operations in your PL of choice.

Put all that together and code the program.

Oh, did you expect the code snippet? Sorry, I don’t do peoples’ homework for them on principle. Homework is for you to learn something. If you can’t be bothered, accept that you’ll fail your class. If you want to pass, LEARN.

ohaa [14]

Answer:

The function definition for this question can be given as:

Function Definition:

bool isSenior(int x )  //function

{  

//function body Or function definition.

//conditional statement

//if statement

if (x >=65)  

{

return true;   //return value true.

}

else  //else statement

{

return false;    //return value false.

}

}

Explanation:

In the above function definition firstly we define a function that isSenior. This function return Boolean value that is true or false in this function we pass the value as the parameter in that function we use the if statement that check the pass value is greater then equal to 65. If the condition is true it return true.else it will return false.

Write a function: function solution(N); that, given a positive integer N, prints the consecutive numbers from 1 to N, each on a
koban [17]

Answer:

<em>The program written in Python is as follows:</em>

def solution(N):

     concat = ""

     for i in range(1,N+1):

           if not(i%2 == 0 or i%3 ==0 or i%5 == 0):

                 print(str(i))

           else:

                 if i%2 == 0:

                       concat= concat+"Codility"

                 if i%3 == 0:

                       concat= concat+"Testers"

                 if i%5 == 0:

                       concat= concat+"Coders"

                 print(concat)

                 concat = ""

N = int(input("Enter a positive integer: "))

solution(N)

Explanation:

This line declares the function

def solution(N):

This line initializes a variable named concat to an empty string

     concat = ""

This line iterates from 1 to the input integer

     for i in range(1,N+1):

<em>This line checks if the current number of iteration is divisible by 2,3 or 5, if no, the number is printed</em>

           if not(i%2 == 0 or i%3 ==0 or i%5 == 0):

                 print(str(i))

<em>If otherwise</em>

           else:

<em>This lines checks if current number is divisible by 2; if yes the string "Codility" is concatenated to string concat</em>

                 if i%2 == 0:

                       concat= concat+"Codility"

<em>This lines checks if current number is divisible by 3; if yes the string "Testers" is concatenated to string concat</em>

<em>                 </em> if i%3 == 0:

                       concat= concat+"Testers"

<em>This lines checks if current number is divisible by 2; if yes the string "Coders" is concatenated to string concat</em>

                 if i%5 == 0:

                       concat= concat+"Coders"

<em>The concatenated string is printed using this line</em>

                 print(concat)

This variable concat is intialized back to an empty string

                 concat = ""

The main method starts here

N = int(input("Enter a positive integer: "))

This line calls the defined function solution

solution(N)
