Round 678(Div 2) reorder problem
By 97rajmath, history, 4 years ago, In English

This problem was quite easy and I coded it and checked it in my local machine. And it was giving me the right answer.(passing all the pretests) but for some reason after submitting the ONLINE_JUDGE was giving me a WRONG_ANSWER response. Here is the code. Can anyone tell me what's wrong in it?

int main(){

int t;
scanf("%d",&t);
while(t--){
    int n;ll m;

    scanf("%d",&n);
    scanf("%d",&m);

    ll a[n],sum=0;
    for(int i=0;i<n;i++)
       scanf("%d",&a[i]);       

    for(int i=0;i<n;i++)
       sum+=a[i];

    if((int)sum==m)
       cout<<"YES"<<endl;
    else
       cout<<"NO"<<endl;
}   
return 0;

}

You have used wrong format specifier for long long. Maybe that can be a reason .

    I defined it before.

    define ll long long

    And everything worked fine in my computer and was giving the correct output. But the Online Judge gave a WRONG_ANSWER response. Don't know why. It was solved when I tried doing it only using int .Then the code was accepted.

      i am talking about "%d" you should use "%lld" . sometime it gives correct output on local machine but this is not the case on online judge.
