Itâ€™s a WA not compilation error.

can you tell why its wrong

Iâ€™m sorry. Iâ€™m a bit busy . So it wonâ€™t be possible for me to read the question and your logic in your code. You may tag anyone from top contributors to help you.

I have changed (long long int compare) to (int compare) still error is coming I think there may be something wrong in logic part as well

my logic :-

If Sergey gets total possible score more than at least n-k students total score then he will be selected

else it is impossible

Please, whenever you say â€śIâ€™ve changed the codeâ€ť, just post the link to the new submission.

Thankyou. This is failing for the exact same reason, for the exact same testcase, as I originally explained.

Just replace your `compare`

function with the one I suggested.

sir please see new submission i have send link above this

i have done according to what you told

No you havenâ€™t XD

Your `compare`

:

```
int compare(const void *p1,const void *p2)
{ int arg1 =*(long long int *)p1;
int arg2 =*(long long int *)p2;
if(arg1<arg2) return -1;
if(arg1>arg2) return 1;
return 0;
}
```

What I asked you to do:

```
int compare(const void *p1,const void *p2)
{
const long long int p1AsLong = *(long long int *)p1;
const long long int p2AsLong = *(long long int *)p2;
if (p1AsLong < p2AsLong)
return -1;
if (p1AsLong > p2AsLong)
return +1;
return 0;
}
```
