11. Binary Search Trees¶ We have already seen two different ways to get key-value pairs in a collection. Recall that these collections implement the map abstract data type.

The two implementations of a map ADT we discussed were binary search on a list , hash tables. The binary search tree was already created , print the key of each node along the way., I just needed to print all the nodes in correct order, which means I had to do a proper inorder traversal of the binary search tree

Definition. A binary search tree is a rooted binary tree, whose internal nodes each store a keyand optionally, an associated value) and each have two distinguished sub-trees, commonly denoted left and right.

The tree additionally satisfies the binary search property, which states that the key in each node must be greater than or equal to any key stored in the left sub-tree, and less than or.
