So on the CF Problem Fox and Names I'm getting something like this:

"Memory limit exceeded on test 15124 ms 262100 KB"

This is weird because I looked at other solutions that do basically the EXACT same thing as me (topological sort) and they passed just fine.

Here's the problem: CF

Here's my solution: [C++] My solution

I'm pretty sure CF judge is not broken. But what is wrong with my solution D: ?
