Question

1. Write a program that prompts the user for an integer, calculates the factorial of the input integer and displays the result as a string with a comma at every third position, starting from the right. Assume that user input is valid. Hint: Think about representing a number as a string. Sample Run 1: Sample Run 3: Enter an int: 0 0! = 1 Enter an int: 10 10! = 3,628,800 Sample Run 2: Sample Run 4: Enter an int: 4 4! = 24 Enter an int: 20 20! = 2,432,902,008,176,640,000

(Python)

Please do NOT solve it by using special functions(like max min, divmod), I have to ask the same questions again and again otherwise, thanks for your understanding.

Answer 1

Answer:

here is the code without using any special functions. Hope this solves your purpose.

fact variable is initialised as 1, then we keep multiplying numbers till n one by one to fact variable.

And print the final answer using some formatting.

n = int(input('Enter an int: '))

fact=1

for i in range(1, n+1):
fact = fact*i

print("{}! = {:,}".format(n, fact))

n = int(input('Enter an int: ')) fact=1 - for i in range(1, n+1): fact = fact*i print("{}! - {:,}".Format(n, fact))||

Output:

Enter an int: 20 20! - 2,432,902,008, 176, 640,000 ... Program finished with exit code o Press ENTER to exit console.
