My issue

I think the output of second testcase should be 3 instead of 2

My code

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

int main() {
	// your code goes here
    int t;cin>>t;
    while(t--){
        int a,b,k;
        cin>>a>>b>>k;
        
    }
}

no ans would be 2
3+1=4
4*2=8
only two operation needed
