Solution:
package lab4problem13;
import java.util.Scanner;
public class Lab4Problem13 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number = input.nextInt();
System.out.println(factorial(number));
}
static int factorial(int a) {
if (a == 1) {
return 1;
} else {
return (a * factorial(a - 1));
}
}
}
