Understanding recursive inorder traversal
Inorder traversal is another fundamental technique for exploring the nodes of a binary tree. In this method, each node is processed in the given sequence: first, the left subtree is visited, then the root node, and finally, the right subtree.
In what scenarios is inorder traversal useful?
Inorder traversal is particularly valuable when dealing with binary search trees (BSTs). It accesses the nodes in ascending order, making it an essential method for sorting and validating the BST property.
