answer:

 

import java.util.Scanner;

public class factorial {
    public static void main(String[] args) {
     Scanner sc=new Scanner(System.in);
     int arr[]=new int[5];
     int arrforfact[]=new int[5];

        for (int i = 0; i < 5; i++) {
            int num=sc.nextInt();
            arr[i]=num;
        }

        for (int i = 0; i < 5; i++) {
            int numm=arr[i];
            int temp=1;
            for (int j = 1; j <=numm ; j++) {

                temp=temp*j;

            }
            arrforfact[i]=temp;


        }
        for (int i = 0; i < 5; i++) {
            System.out.println(arrforfact[i]);
        }

    }
