Good integer (Posted on 2021-05-21) Difficulty: 3 of 5
We call a positive integer good if it doesn’t have a zero digit and the sum of the squares of its digits is a perfect square. For example, 122 and 34 are good and 304 and 12 are not not good. Prove that there exists an n-digit good number for every positive integer n.
