Use of Sum of digit is Pallindrome or not test

The problem requires us to determine if the digit sum of a given number is a palindrome or not. To do this, we first calculate the digit sum of the number, which is done by summing up all the digits in the number. We can obtain the individual digits by repeatedly dividing the number by 10 and taking the remainder until we reach zero.

Next, we check if the digit sum is a palindrome or not. To do this, we reverse the digit sum and compare it with the original digit sum. If they are the same, then the digit sum is a palindrome and we return "YES". Otherwise, we return "NO".
