# 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?

# learned about itertools from problem 23. Python is wonderful
