Traversing a binary search tree, Data Structure & Algorithms

Assignment Help:

Binary Search Tree let three types of traversals by its nodes. They are:

Pre Order Traversal
In Order Traversal
Post Order Traversal

In Pre Order Traversal, we carry out the following three operations:

Visit the node
Traverse the left subtree in preorder
Traverse the right subtree in preorder

In Order Traversal, we carry out the given three operations:

a) Traverse the left subtree in inorder

b) Visit the root

c) Traverse the right subtree in inorder.

In Post Order Traversal, we carry out the three operations which are following:

a. Traverse the left subtree in postorder

b. Traverse the right subtree in postorder

c. Visit the root
