thanks you all for your feedback .. but I had implemented something in clojure which I knew would be much faster in say c++ .. and now was regretting it .. and was really looking at all weird locations in desperation.. but now I realized I was doing something in a very wrong inefficient (algorithmically ) way .. now things seem better..
