Hello guys, Recently I was trying to take preparation for google kickstart. And while solving a problem of kickstart-2020 I faced a problem with my solution. I was able to pass the sample tests but I was getting WA in test set 1. Can anyone please help me figure out the problem with my code. Here is my code-

include <bits/stdc++.h>

using namespace std;

int solve(){ int n,b; cin>>n>>b; int ar[n]; for(int i=0;i<n;i++){ cin>>ar[i]; } sort(ar,ar+n); int a=0; int sm=ar[0]; while(sm<=b){ a+=1; sm+=ar[a]; } return a; }

int main(){ int t,i=1; cin>>t; while(t--){ int ans=solve(); cout<<"Case #"<<i<<": "<<ans<<'\n'; i++; } return 0; }
