A long code without any explanation. Don't be surprised that you don't get help.

EDIT — The next paragraph is bullshit, don't read it.

I have read your code and I think its complexity is O(n·m) because of line:
p=lower_bound(h[x].begin(),h[x].end(),l);
Note that lower_bound() is linear for vectors. Write your own binary search there.

Replace endl with "\n".
