The Problem

The “reverse and add” method is simple: choose a number, reverse its digits and add it to the original.

If the sum is not a palindrome (which means, it is not the same number from left to right and right to left),

repeat this procedure.

For example:

195 Initial number

591

—–

786

687

—–

1473

3741

—–

5214

4125

—–

9339 Resulting palindrome
