WebIn-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 set up the binary search tree (hence the name). Post-order traversal while deleting or freeing nodes and values can delete or free an entire binary tree. WebTree: Postorder Traversal. Problem. Submissions. Leaderboard. Discussions. Editorial.

Binary Tree: Post-order Traversal by Abhimanyu Singh

WebFor a complete binary tree with n nodes, such operations run in (lg n) worst-case time. If the tree is a linear chain of n nodes, however, the same operations take (n) worst-case time. We shall see in Section 13.4 that the height of a randomly built binary search tree is O(lg n), so that basic dynamic-set operations take (lg n) time. WebRealization of binary search tree.
