-- Problem 24
--
-- A permutation is an ordered arrangement of objects. For example, 3124 is
-- one possible permutation of the digits 1, 2, 3 and 4. If all of the
-- permutations are listed numerically or alphabetically, we call it
-- lexicographic order. The lexicographic permutations of 0, 1 and 2 are:
--
-- 012   021   102   120   201   210
--
-- What is the millionth lexicographic permutation of the digits 0, 1, 2,
-- 3, 4, 5, 6, 7, 8 and 9?
