Why it isb not passing any test case

#1

#include
using namespace std;
int subsetSum(int arr[], int n, int i, int sum, int count)
{
if (i == n) {

    if (sum == 0) {
        count++;
    }
    return count;
}
count = subsetSum(arr, n, i + 1, sum - arr[i], count);
count = subsetSum(arr, n, i + 1, sum, count);
return count;

}
int main()
{
int t;cin>>t;
while(t–){
int n;cin>>n;int arr[n];
for(int i=0;i<n;i++)cin>>arr[i];
int sum=0;
if(subsetSum(arr, n, 0, sum, 0)){cout<<“Yes”<<endl;}
else cout<<“No”<<endl;
}
}

Hello @argus please wait i am checking your code :

@argus i have corrected your code:


you have initialised as your sum 0 then there is possibility that it reaches to the end and as your sum is zero then it must be givin the answer true for that as well.
