Lychrel number

A Lychrel number is a natural number that is not known to form a palindrome through the iterative process of reversing its digits and adding the result to the original number. A number is considered a palindrome if it reads the same forwards and backwards (for example, 121 or 12321). The Lychrel process typically involves the following steps: 1. Take a natural number n. 2. Reverse its digits to get a new number. 3. Add the reversed number to the original number.
