Simplest Binary Tree Traversal Trick For Preorder, Inorder and Postorder | By Jaishri Gupta | PSUs

Описание: In this video lecture, we will discuss - How to perform tree traversal.

In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (checking and/or updating) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited. The following algorithms are described for a binary tree, but they may be generalized to other trees as well.
Pre-order traversal can be used to make a prefix expression (Polish notation) from expression trees: traverse the expression tree pre-orderly. For example, traversing the depicted arithmetic expression in pre-order yields "+ * A - B C + D E".

Post-order traversal can generate a postfix representation (Reverse Polish notation) of a binary tree. Traversing the depicted arithmetic expression in post-order yields "A B C - * D E + +"; the latter can easily be transformed into machine code to evaluate the expression by a stack machine.

In-order traversal is very commonly used on binary search trees because it returns values from the underlying set in order, according to the comparator that sets up the binary search tree.
