Predict output of following program
#include <iostream>
int fun(int n)
{
if (n == 4)
return n;
else return 2 * fun(n + 1);
}
int main()
{
std::cout << fun(2);
return 0;
}
#include <stdio.h>
int fun(int n)
{
if (n == 4)
return n;
else return 2*fun(n+1);
}
int main()
{
printf("%d", fun(2));
return 0;
}
public class Main {
public static int fun(int n) {
if (n == 4)
return n;
else return 2 * fun(n + 1);
}
public static void main(String[] args) {
System.out.println(fun(2));
}
}
def fun(n):
if n == 4:
return n
else:
return 2 * fun(n + 1)
print(fun(2))
function fun(n) {
if (n === 4)
return n;
else return 2 * fun(n + 1);
}
