Problem of the Week
Problem D
Again in Reverse

A palindrome is a word or phrase which reads the same forwards and backwards, ignoring spaces and punctuation. Numbers which remain the same when the digits are reversed are also considered to be palindromes. For example \(9\,357\,539\), \(6116\), and \(2\) are all palindromes.

How many positive integers less than \(1\,000\,000\) are palindromes?

Signs with the phrases "No lemons, no melon" and "Was it a
car or a cat I saw?"
