Binary Search Tree Traversal – Inorder, Preorder, Post Order for BST

WebMar 24, 2024 · Binary trees are a form of hierarchical data storage that uses tree traversals as the primary method of visiting all the constituent nodes for searching, sorting, and other purposes. Understanding the various methods used for tree traversals can help you complete basic operations on a binary tree. WebTo construct the complete binary search tree, recursively repeat the above steps for postorder sequence {8, 12, 10} and {16, 25, 20}. The algorithm can be implemented as follows in C, Java, and Python: C Java Python Download Run Code Output: Inorder traversal of BST is 8 10 12 15 16 20 25
