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?

Your job is to measure 45 minutes if you have only two cords and matches to light the cords.

2. Each cord burns from end to end in exactly one hour.

Describe your way of measuring the 45 minutes.
