SortedList, SortedSet, and SortedMap — zero runtime dependencies, inspired by Python's sortedcontainers.

SortedList

A list that keeps insertion order sorted automatically. Binary-search lookups, positional access, range queries.

A sorted set with no duplicates, plus set-theory operations — union, intersection, difference, isSubsetOf.

A dictionary ordered by key, with the same range-query and positional-access API as the other two.
