Given a Number Find its Factorial

Given a number, you have to find its factorial.

For Example: 
                    If the input is "4" the factorial would be "4 * 3 * 2 * 1" which is, "24"
                    If the input is "3" the factorial would be "3 * 2 * 1" which is, "6"

Python Implementation:

#Using User-Defined Function def fact ( n ) : # If the value of becomes "0" or "1", return 1 if n == 0 or n == 1 : return 1 # Recursively call and multiply numbers like 5* 4* 3* 2* 1 until it reaches 1 return n * fact ( n - 1 ) # Get the number of test cases from the user t = int ( raw_input () ) # Do until the number of test cases becomes "0" while ( t > 0 ) : # Get an integer from the user to find its factorial n = int ( raw_input () ) ''' Call the fact() function to find the factorial of "n" and print the return value of the function ''' print fact ( n ) # Decrement number of test cases after evaluation of every test case t - = 1 #Python Implementation using in-built function: # Import the factorial method from "math" library from math import factorial # Get the number of test cases from the user t = int ( raw_input () ) # Do until the number of test cases becomes "0" while ( t > 0 ) : # Get an integer from the user to find its factorial n = int ( raw_input () ) # Print the factorial of the number "n" print factorial ( n ) # Decrement number of test cases after evaluation of every test case t - = 1
