I agree with you, I get the point and it is correct.
In the above example it is not clear first of all where do we look for those
English words. Assume you have them in string, you again need the offset -
start of word and then check the fifth and seventh position, so further
iteration. 
I never bothered to look in stdc++ or libc how it is implemented - for
example c++ string at() operation. Can someone enlight us pls?
