"""
A Kaprekar number is a positive integer where the representation of its square can be partitioned into
two parts that add up to the original number.
For example, 9 is a Kaprekar number because 9^2 = 81, and 8 + 1 = 9.

input:45
output:True
Reason: The square of 45 is 2025. Splitting this into two parts gives us 20 and 25, which add up to give
        us back our original number, 45. Hence, it's a Kaprekar Number.

Input:297
Output:True

Input:46
Output:False
