## Problem Statement

#### You are given a string 'S'. A string is called a split string if it follows the conditions define below.

``````1. It can be divided into 'K' contiguous substrings such that the first letter of these substrings is the same for all the substrings.
2. It can be divided into 'K' contiguous substrings such that the first letter of these substrings is distinct for all the substrings.
``````

#### Return 1 if 'S' is a split string otherwise return 0.

##### For Example:-
``````Let 'N' = 6, 'K' = 2, 'S' = "pppdpa".
It can be divided into "pp" and "pdpa", the first letter of the strings is same.
It can be divided into "ppp" and "dpa", the first letter of the strings is distinct.
