Problem 45. Make a Palindrome Number

Created by Cody Team in Community

Some numbers like 323 are palindromes. Other numbers like 124 are not. But look what happens when we add that number to a reversed copy of itself.

    124
  + 421
   ----
    545

Let's try another.

    150
  + 051
   ----
    201

No, that didn't work, but what if we keep going?

    201
  + 102
   ----
    303

There, it became a palindrome again. Given a, return b = find_palindrome(a) such that b is the palindrome number that eventually results from repeated reversals and additions of a.

Example:

 Input  a = 150
 Output b is 303
