What is traversal of Tree? tccicomputercoaching.com

Traversal is a process to visit all the nodes of a tree and may print their values too. Because, all nodes are connected via edges (links) we always start from the root (head) node. That is, we cannot randomly access a node in a tree.

There are three ways which we use to traverse a tree -

• In-order Traversal
• Pre-order Traversal
• Post-order Traversal

Generally, we traverse a tree to search or locate a given item or key in the tree or to print all the values it contains.
