* Rename all Project Euler directories: Reason: The change was done to maintain consistency throughout the directory and to keep all directories in sorted order. Due to the above change, some config files had to be modified: 'problem_22` -> `problem_022` * Update scripts to pad zeroes in PE directories

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?
