A sea diver is a real show-off. He showed everyone that he can hold his breath underwater for 15 minutes.

He responded that he will give me 100$ if I would be able to do it. I won 100$.

What did I do?

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?

What can you catch but never throw?
