Use Rabin-Karp Algorithm. It uses string hashing.

    Isn't the time limit too strict for Rabin-Karp?

      Rabin-karp complexity is O(n*m) and this problem time limit is 0.100s. So what will be the better approach?

        I couldn't come up with anything using string hashing, but the problem might be solved using suffix array with complexity O(MlogM + N*logM). (still not sure if it's gonna pass since time limit is too tight) You can check it out here.
