1 VOUR CODE HERE n! = nx (n - 1) x (n - 2) x .. x 3 x 2 x 1 We won't worry about O! for the purposes of this challenge: we will only assume positive values of n. 4 DO NOT MODIFY # 5 n= int(input("Enter n: ")) ask user for number 6 print () 7n fact factorial(n) 8 print(n_fact) 9 # DO NOT MODIFY N * print empty line * compute n! *print the result Task: Compute n! In this part of the assignment, you will write a recursive function that, when given a number, will print the factorial of that number. When the program is executed, it will ask the user to enter a number, and it will store it a variable: n. This is done for you in the code we have provided at the bottom of the program (between the two # DO NOT MODIFY comments). Below the # YOUR CODE HERE comment, you will write a recursive function called factorial which has a single parameter (n) and which returns n! (.e., n factorial). Your function must be recursive. For example, if you run your program as follows: TEXT Enter n: 5 Your…
