I can't to find it.
Please help me.

lineCmp, just as any other comparator, mustn't take references as arguments. Const references are fine, though.

set iterators are const iterators. You can't change an object once it's in a set.

did you get your compile problem resolved?

I'm having a compile error that is similar to yours. It compiles fine on my machine, but it doesn't compile on the judges machine. The only thing that I can think of that might have caused the compile error is that I used Vectors and I used a built in FIND function. It's the same find function taht you used here. I'm suspecting that might be the reason for the compile error.

Someone suggested that it might be the .clear() function used to clear vectors. I replaced that statement with something else, but it still didn't work.

How did you fix yours?

There are no Vectors or FIND in gcc. There are vectors and find, though.
