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?
|
||||||
|
=#
|
||||||
|
digits = [0,1,2,3,4,5,6,7,8,9]
|
||||||
|
_permutations = nthperm(digits, 1_000_000)
|
||||||
|
return join(_permutations)
|
||||||
|
end

@time Problem24()
|

println("")

println("Result for Problem 24: ", Problem24())
