Every number is the sum of at max three palindromic numbers. A palindromic number is a number, which remains the same when its digits are reversed, such as 232. Examples: 21 = 11 + 1 + 9, 908 = 797 + 111. For small numbers it is an easy task to find these palindromes. But it is a bit of puzzling to find such numbers for larger numbers. Take the challenge in many different levels!
