Pre-Order Traversal in Binary Search Trees

Explore how to perform pre-order traversal in binary search trees by visiting nodes in root-left-right order. Understand the recursive method to traverse and print all nodes, learn the Java implementation, and grasp its O(n) time complexity to prepare for coding interviews.

We'll cover the following...

Pre-Order Traversal

In this type, the elements are traversed in “root-left-right” order. We first visit the root/parent node and then the children; First the left child and then the right one.

The following steps are required to perform Pre-Order Traversal, starting from the root node:

  1. Visit the current node and display its data.

  2. Traverse the left sub-tree of currentNode, recursively using the PreOrder() function.

  3. Traverse the right sub-tree of ...
