Once upon a time, there was a castle on a square island. The entire island was surrounded by a 14m wide trench.

The Romans still managed to cross the trench. How did they do it?

One day, I thought of ways that can be used for creating a palindrome. So I decided that I will turn into a larger number by adding the reversed digits to the original number and keep doing it till I finally obtained a palindrome.

I am not sure if this process will always result in a palindrome eventually but I was able to produce a four-digit palindrome. Can you guess my starting number?
