hi @kumarankesh5feb
try this -->

#include <bits/stdc++.h>
using namespace std;

long long int fib(long long int n)
{
    if (n <= 1)
        return n;

    return fib(n - 1) + fib(n - 2);
}

int main()
{
    int testCases;
    cin >> testCases;
    int k = 1;

    while (testCases--)
    {
        int n;
        cin >> n;
        cout << "#" << k++ << " : " << fib(n+2) << endl;
    }

    return 0;
}
#3

ok…
expected o/p was–>

#1 : 2
#2 : 3
#3 : 5

ur o/p -->

2
3 
5

so difference is clearly visible… ur logic was correct but o/p was not being printed in the format in which its expected…
corrected code -->

Hey is there anything else??
