Inorder... WebFeb 18, 2024 · In the tree data structure, traversal means visiting nodes in some specific manner. There are nodes2 types of traversals. Generally, this kind of traversal is based on the binary tree. A binary tree means each node can have a maximum of 2 nodes. A binary tree is a well-known data structure. There’s also a Binary Search tree (BST).
