Project Euler Problem #4 – Palindromic Numbers
Problem 4 asks us to “Find the largest palindrome made from the product of two 3-digit numbers.” First we know our maximum factor is 999, which safely puts our possible palindromes in the 6 digit range. This is important because of the proof that all even-digit palindromes have 11 as a factor. I use this…
