## Byomkesh needs to check for equality ##
Byomkesh : Ajit babu, are you game to solve a challenge ?
Ajit : Do I have a choice ?
Byomkesh : Ha, ha, hah. Do not feel so resigned. Challenges are good for the little grey cells as Hercule Poirot would say.
Ajit : I am no Hercule Poirot. Or Byomkesh Bakshi for that matter.
Byomkesh : Yes. yes. You are the one and only Ajit Kumar Mitra !
Ajit : Ok. Let us hear your challenge.

Byomkesh : I have this string of characters. The string has only two types of characters - either 'A' or 'B'.
They can be repeated any number of times. I need to find out if the string has equal number of 'A's and 'B's or not.

Ajit : This is easy for a change ! Just iterate through the string, count the number of each character and compare at the end.
Byomkesh : Not so fast my friend. There are constraints.
