Problem Description
Cloud018 is very upset that many people on the Internet usually mix uppercase and
lowercase letters in one word. That's why he decided to invent an extension for his favorite
browser that would change the letters' case in every word so that it either only consisted of
lowercase letters or only consisted of uppercase ones. And he wants to change as few letters as
possible in the word.
For example, the word "HoUse" must be changed to "house", and the word "ViP", to "VIP".
If a word contains an equal number of uppercase and lowercase letters, you should replace all the
letters with lowercase ones. For example, "maTRIx" should be changed to "matrix".
You task is to use the given method to change the given word.
