Challenge 4: Largest Palindrome Product #7

Closed andrew-field closed 5 years ago

andrew-field commented 6 years ago

A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.

Find the largest palindrome made from the product of two 3-digit numbers.

A basic brute force method. This can probably be optimised. One could make reasonable assumptions to assume that the answer has 6 digits perhaps to cut down on the number of trials but this solution remains generic.

Updated to use the new library functions to find the digits of a number.
