Palindrome in 4 steps (Posted on 2018-06-06) Difficulty: 3 of 5
I took a certain 3-digit number, reversed it, got another 3-digit number, and added the two.
The sum was not a palindrome.
I repeated the process, which resulted in another 3-digit number that was still not a palindrome.
Repeating the process twice more I got a 4-digit number, which was a palindrome finally.

What was the 3-digit number we started with the second time?
