Given two numbers a and b and the task is to check whether the concatenation of a and b is a perfect square or not.
Input: a = 1, b = 21
121 = 11 × 11, is a perfect square.
Input: a = 100, b = 100
100100 is not a perfect square.
Approach: Initialize the number as strings initially and concatenate them. Convert the string to a number using Integer.valueOf() function. Once the string has been converted to a number, check if the number is a perfect square or not.
