I've been coding up a bunch of different binary search tree implementations recently (AVL, splay, treap) and am curious if there's a particularly "good" way to write an iterator to traverse these structures. Calling next() will return the next smallest number in the BST. This is a standard inorder traversal of a tree. Previous Next If you want to practice data structure and algorithm programs, you can go through Top 100+ data structure and algorithm interview questions. 2313 268 Add to List Share. There are 3 solutions for solving this problem. So, we need to implement an iterator class with two functions namely next() and hasNext().The hasNext() function returns a boolean value indicating whether there are any more elements left in the binary search tree or not. Binary Search Tree Iterator. This is 2nd part of java binary tree tutorial. This is 4th part of java binary tree tutorial. Your iterator will be initialized with the root node of a BST. Your iterator will be initialized with the root node of a BST.

Inorder Successor in BST. Java Solution Prev. Implemented iterator for a binary tree and "pre" "in" and "post" order flavors.

Solution.

Medium. Medium. Note: next() and hasNext() should run in average O(1) time and uses O(h) memory, where h is the height of the tree. Problems.
