    When thinking of a "three digit number" I think of one that requires three digits rather than one that's made to be three digits arbitrarily. That's why in the computer program to find the solution I allowed the middle digit to be zero but not the first, as the number formed by the second and third digits was not specified to be necessarily a 2-digit number.
