If you really want help you have to write your code clean and readable.

I'm sure now one will waste his/her time to read this mess!

Here's a bug in your code, you choose to sort ooo till max element while you should only sort till the dth-element.

so replace sort(ooo,ooo+max,option);

with sort(ooo,ooo+d,option);

and that should fix your first bug, though there are more bugs and you will reach WA on test 3. Let me know if you need more help debugging, I do recommend that you try debugging on your own as it is an important process to go through.

I also recommend better naming if you want to get help from others. I took more than the usual time to debug this as it is really difficult to understand your program with such naming.
