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.
