An Analysis of the meaning is about to give a string of cows, and then find a substring that spans the longest distance so that there are as many white cows as those in the range. White Cows can be painted as white cows.

Since "White ox can be painted as a flower Ox", we need to find the longest substring so that the length is even and the number of white ox> = flower ox.
