using namespace std;



int main() {
    int t;
    cin >> t;
    while (t--) {
     int n;
     cin>>n;
     int a[n];
     int f=0;
     long long int count=0;
     for(int i=0;i<n;i++) {
          cin>>a[i];
          
     }
     for(int i=0;i<n;i++) {
             if(a[i]!=0){
               f=i;
               break;
             }
     }
     if(f==n-1){
          cout<<"0"<<endl;
          
     }
     else{
           for(int i=f;i<n-1;i++){
               if(a[i]==0){
                    count+=1;
                    //cout<<"This statement is running for a[i]==0"<<endl;
               }
               else{
                    count+=a[i];
                    //cout<<"This statement is running for a[i]!=0"<<endl;
               }
               //cout<<"Value of count after "<<i<<"is : " <<count<<endl;
           }
           //cout<<"Final value of count is : "<<endl;
           cout<<count<<endl;
     }
     

      
    }

What about the case when all elements of a are 0 (0 0 0 0 for example)? answer should be 0 in that case right? but your code will return the count of 0’s - 1.
Hope this helps :slight_smile: ! (you are on the right track just a small fix is required!)
