Problem 44316. Pandigital Multiples of 11 (based on Project Euler 491)

Created by James in Community

A "Pandigital number of order X" is one that contains all of the numbers from 0 to X, but with no leading zeroes. If X>9, the cycle 0-9 repeats itself. For example, 2310 is a Pandigital number of order 3 (0-3), while 120345678901 is a Pandigital number of order 11, with the "01" at the end of the number representing 10 and 11, respectively (10 and 11 mod 10, essentially). 0321 is not a Pandigital number, as it has a leading zero.

Given a number X, determine how many pandigital numbers of that order are divisible by 11. You do not need to return the numbers themselves, just how many of them there are.
