I was trying this problem of ZCO Practice Contest and have a solution to it here.Can anyone find any bug in this because i am getting WA?

Your compare function is incorrectly written. It will work for integers but not for long long. Hence, rewrite it to something like,

int cmpfunc (const void * a, const void * b){
    if( * (long long int * )a - * (long long int * )b < 0 )
        return -1;
    if( * (long long int * )a - * (long long int * )b > 0 )
        return 1;
    if( * (long long int * )a - *(long long int * )b == 0 )
        return 0;

Check it out here if you’re still having any problem with the comparator code.

Hope it works! :slight_smile:

There’s some problem in formatting, I’ll fix it soon. The asterisks aren’t visible somehow.
I’ve given you the link if it still doesn’t work, you may check it out.

logic is not correct because it does not solve even first case of problem itself …
according to your logic it should be 53 because after sorting this would be the last element in the sorted array … i am trying this problem but i am getting the TLE… if i would be able to solve the problem … i will tell you soon… thanks. Hope this helps… If not please tell where i lag.
