#Understainding Trie in Ruby
#source https://github.com/kanwei/algorithms/blob/81987340f24edb7fd8ca60885b1f04d1907f8c03/lib/containers/trie.rb
=begin rdoc
    A Trie is a data structure that stores key value pairs in a tree-like fashion. It allows
    O(m) lookup speed, where m is the length of the key searched, and has no chance of collisions,
    unlike hash tables. Because of its nature, search misses are quickly detected.
    
    Tries are often used for longest prefix algorithms, wildcard matching, and can be used to
    implement a radix sort.
