# Also do the 2026.05.06 homework
#
# Implement insertion, removal and search in a binary search tree.
# Properties of binary search trees:
# - Each node has at most two children
# - The left subtree of a node contains only nodes with values less than the node's value
# - The right subtree of a node contains only nodes with values greater than the node's value
#
# Example of what such a tree would look like:
# 10
# / \
# 5 15
# / \ \
# 3 7 20
#
# Example of an *invalid* tree:
# 10
# / \
# 5 15
# / \ \
# 3 7 20
# \
# 12
#
# Don't worry about balancing the tree for now, we will cover that later
