I have a difficult to resolve this exercise
Someone can help me
package fr.codegym.task.task15.task1531;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.math.BigDecimal;
/*
Factorielle
*/
public class Solution {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
int input = Integer.parseInt(reader.readLine());
reader.close();
System.out.println(factorial(input));
}
public static String factorial(int n) {
//écris ton code ici
double f = 1;
for (int i=1; i<=n; i++)
f=f*i;
return f+"";
}
public static double calculeFactoriel(int n ) {
// sortie
if (n == 0 ) {
return 1;
} else {
return n * calculeFactoriel( n - 1 ) ;
}
// continuer
}
}
