What's the best algorithm for comparing two arrays to see if they have the same members?
Assume there are no duplicates, the members can be in any order, and that neither is sorted.
compare(
[a, b, c, d],
[b, a, d, c]
) ==> true
compare(
[a, b, e],
[a, b, c]
) ==> false
compare(
[a, b, c],
[a, b]
) ==> false
