Solution 1: Factorial Calculation using Loops Code: import java.util.Scanner; public class FactorialUsingLoop { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Taking user input System.out.print("Enter a number: "); int num = scanner.nextInt(); //...
Here, we are going to implement logic to find factorial of given number in Python, there are two methods that we are going to use 1) using loop and 2) using recursion method.
Note: To test the program for a different number, change the value of num. Here, the number whose factorial is to be found is stored in num, and we check if the number is negative, zero or positive using if...elif...else statement. If the number is positive, we use for loop and...
Now let's see how we can calculate factorial using the while loop. Here's our modified method: public static int getFactorialWhileLoop(int n){ int result = 1; while (n > 1) { result = result * n; n -= 1; } return result; } This is pretty similar to the for loop. Except ...
Java developer would know when to stop. Life is too short to build castles in the clouds. He’d know that a simple looped solution is more than sufficient, and of course he handles negative numbers. (Note that in our recursive solutions, a negative number results in an endless loop.) ...
In the following PHP program factorial of number 5 is calculated. This is a simple program using for loop. This for loop is iterated on the sequence of numbers starting from the number till 1 is reached. Code: <?php //example to calculate factorial of a number using simple for loop ...
