# 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?
