Write function that ask for input from a user. Use this input as input for the countdown function that we wrote using the while loop. If the user types 'end', the program exits, otherwise it keeps going.

Written in Python:

def myfunction():

     userinput = input("User input: ")

     while(userinput != "end"):

           countdown(userinput)

           userinput = input("User input: ")

Explanation:

This line defines the function

def myfunction():

           This line prompts user for user input

           userinput = input("User input: ")

           The following while loop checks if userinput is not "end". It continues execution until user input "end"

           while(userinput != "end"):

                       countdown(userinput) If yes, the input is passed to the countdown function for execution

                       This line prompts user for another user input

                       userinput = input("User input: ")

Please note the above code segment assumes that countdown() function has already been written and defined

the answer is d.
