HashSet、やってみた。

サンプルコード

set1 = Enum.into 2..6, HashSet.new
IO.inspect set1


IO.inspect "delete(set, term)"
IO.inspect Set.delete set1, 3


IO.inspect "difference(set1, set2)"
set2 = Enum.into 4..8, HashSet.new
IO.inspect Set.difference set1, set2


IO.inspect "disjoint?(set1, set2)"
IO.inspect Set.disjoint? set1, set2
set3 = Enum.into 7..10, HashSet.new
IO.inspect Set.disjoint? set1, set3


IO.inspect "equal?(set1, set2)"
set4 = Enum.into 7..10, HashSet.new
IO.inspect Set.equal? set1, set4
IO.inspect Set.equal? set3, set4


IO.inspect "intersection(set1, set2)"
IO.inspect Set.intersection set1, set2
IO.inspect Set.intersection set1, set3


IO.inspect "member?(hashset, term)"
IO.inspect Set.member? set1, 2
IO.inspect Set.member? set1, 7


IO.inspect "put(hashset, term)"
IO.inspect Set.put set1, 7
IO.inspect Set.put set1, 6


IO.inspect "size(hashset)"
IO.inspect Set.size set1
set5 = Enum.into 1..10, HashSet.new
IO.inspect Set.size set5


IO.inspect "subset?(set1, set2)"
IO.inspect Set.subset? Enum.into(2..4, HashSet.new), Enum.into(2..5, HashSet.new)
IO.inspect Set.subset? Enum.into(2..5, HashSet.new), Enum.into(2..4, HashSet.new)


IO.inspect "union(set1, set2)"
IO.inspect Set.union Enum.into(2..4, HashSet.new), Enum.into(4..8, HashSet.new)
