Biggest palindrome (Posted on 2019-02-21) Difficulty: 3 of 5
For n = 1: 9 is the largest palindrome which is the product of two 1-digit numbers.
9 = 3*3

For n = 2: 9009 is the largest palindrome which is the product of two 2-digit numbers.
9009 = 91*99

Continue for n=3, 4, ..., etc.

How far can you go?
