NHAY is a SPOJ question involving pattern search. The Link: http://www.spoj.com/problems/NHAY/

My solution gives me TLE. Here is my code: https://ideone.com/A2N6An What are some optimizations that I can apply on my code?

Every time you call strlen(), it works for O(len), so your code works for O(n^2).

And please, format your code. It's really hard to read it.

    Doesn't Optimizer change the code to a way you said ? I thought c++ optimizer have such things that can detect unchanged values in loops and doesn't recalculate them every time for conditions.
