some useful datastructure implementations

Stacks

• ImmutableStack
  • Something I saw in a Kevlin Henney video and thought it was pretty cool. The actual video https://youtu.be/APUCMSPiNh4?t=2673

Heaps

• Binary Heap

Trees

• BinarySearchTree

  • Avl implementation which permits duplicate elements

• PrefixTrie

  • Pretty basic implementation of a Re'trie'val tree which can match prefixes.

• SuffixTrie

  • A simple extension of the PrefixTrie which can also match suffixes at the cost of double the nodes. I'm working on a more advanced version.
