Trees usage

Every implemented tree inherits AbstractTree class. That means you can use every method declared in AbstractTree, e.g get, contains, insert, delete, __iter__

Example:

from core.trees.red_black_tree import RedBlackTree

population_tree = RedBlackTree()

population_tree["Lviv"] = 1000000
population_tree["Kyiv"] = 2900000
population_tree["Dnipro"] = 870000

print(population_tree["Kyiv"])
# 2900000

print("Lviv" in population_tree)
# True

print("Kharkiv" in population_tree)
# False

population_tree.delete("Dnipro")

print("Dnipro" in population_tree)
# False

print(list(population_tree))
# [('Kyiv', 2900000), ('Lviv', 1000000)]
