When run on each test case individually, your code appears to be correct. However, when run on the entire test file, it returns a WA. The most common reasons for this are that you do not have a newline after each test case, or you do not reinitialize some variables in each test case. Getting this error for above code for Andrew and the Meatballs please help me fix this issue

@omthorve90
use long long int rest of your code is correct.
i have corrected it in your code

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

int main() {
int t;
cin>>t;

while(t--){
    long long int n,m;
    cin>>n>>m;
    
    long long int p[n];
    for(int i=0;i<n;i++){
        cin>>p[i];
    }
    
    sort(p,p+n);
    
    long long int sum = 0;
    int flag = 0;
    
    for(int i=0;i<n;i++){
        sum+=p[n-i-1];
        if(sum>=m){
            cout<<i+1<<endl;
            flag = 1;
            break;
        }
    }
    
    if(flag==0){
        cout<<-1<<endl;
    }
    
}
return 0;
}
