题目描述

Given a number N, write a program to check whether given number is Adam Number or not.
Adam number is a number when reversed, the square of the number and the square of the reversed number should be numbers which are reverse of each other.

Example 1:
Input:
N = 12
Output:
YES
Explanation:
12^{2} = 144 and 21^{2} = 441. 144 reversed
gives 441, So, it's an Adam Number.
Example 1:
Input:
N = 14
Output:
NO
Explanation:
14^{2} = 196. 196 reversed gives 691,
which isn't equal to 41^{2} So,
it's not an Adam Number.

Your Task:
You don't need to read input or print anything. Your task is to complete the function checkAdamOrNot() which takes an Integer N as input and returns the answer as "YES" if it is a Adam, number. Otherwise, returns "NO".

Expected Time Complexity: O(|N|)
Expected Auxiliary Space: O(1)

Constraints:
1 <= N <= 10^{4}
