Close Scanner:The scanner is closed to free up system resources. Solution 2: Factorial Calculation using Recursion Code: import java.util.Scanner; public class FactorialUsingRecursion { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Taking user input Syste...
To find the factorial, fact() function is written in the program. This function will take number (num) as an argument and return the factorial of the number.# function to calculate the factorial def fact(n): if n == 0: return 1 return n * fact(n - 1) # Main code num = 4 #...
If you'd like to read more about getting user input in Java - read our Guide to the Scanner class. Let's test our method and print the results: Scanner scanner = new Scanner(System.in); int inp; System.out.println("Enter a number: "); inp = Integer.parseInt(scanner.nextLine()); ...
# Python program to find the factorial of a number provided by the user. # change the value for a different result num = 7 # To take input from the user #num = int(input("Enter a number: ")) factorial = 1 # check if the number is negative, positive or zero if num < 0: prin...
