    Do you really write all your code like this?

    Has someone taken the case where the person might walk first N then W then S and the E into account? Meaning that he walks in a circle so baically he comes back to the point where he started after walking a circle. Ex- ['N','S','N','S','N','S','N','W','S','E'].
    If so can someone share their code?
