From c0c719f2b676a15a09c6f85363d3f628d3432e77 Mon Sep 17 00:00:00 2001 From: Speiger Date: Fri, 8 Jan 2021 21:12:20 +0100 Subject: [PATCH] Next big batch of features. -Added: Tests for IntSortedSet, IntNavigableSet. -Added: Test Classes for: Open/Custom/Linked HashSet, TreeSets, ArraySet -Changed: MemFreeMergeSort got improved by a lot. -Fixed: Bugs that the tests uncovered. -Note: TreeSets still have issues.
