DIGITAL SEARCH TREES

DIGITAL SEARCH TREES. Definition. A digital search tree is a binary tree in which each node contains one element. The element-to-node assignment is determined by the binary representation of the element keys.

Binary Search Trees

Binary Search Trees. Adding and Removing. Adding to the Tree. Adding to a binary search tree is fairly straightforward. You will begin at the root, and as you move down to each node, there are three cases: 1. The value to be added is equal to the value of the current node.
