What is a BST iterator?
Binary Search Tree Iterator. Implement the BSTIterator class that represents an iterator over the in-order traversal of a binary search tree (BST): BSTIterator(TreeNode root) Initializes an object of the BSTIterator class. The root of the BST is given as part of the constructor.
What is BST insertion?
Insert function is used to add a new element in a binary search tree at appropriate location. Insert function is to be designed in such a way that, it must node violate the property of binary search tree at each value. Allocate the memory for tree.
How do you iterate through BST?
Binary Search Tree Iterator in C++
- There are two methods next and hasNext,
- The next() method will be like −
- curr := stack top element, and pop top element.
- if right of curr is not null, then push inorder successor from the right of node.
- return value of current.
- The hasNext() method will be like −
What is time complexity of insert in BST?
In general, time complexity is O(h) where h is height of BST. Insertion: For inserting element 0, it must be inserted as left child of 1. Therefore, we need to traverse all elements (in order 3, 2, 1) to insert 0 which has worst case complexity of O(n). In general, time complexity is O(h).
How many types of insertion are performed in a binary tree?
Two kinds of
Explanation: Two kinds of insertion operation is performed in a binary tree- inserting a leaf node and inserting an internal node.
What is BST and explain it with a real life example?
A Self-Balancing Binary Search Tree is used to maintain sorted stream of data. For example, suppose we are getting online orders placed and we want to maintain the live data (in RAM) in sorted order of prices. For example, we wish to know number of items purchased at cost below a given cost at any moment.
What is complexity of binary search tree?
The space complexity of a binary search tree is O ( n ) O(n) O(n) in both the average and the worst cases.
What are iterative statements in Java?
The java programming language provides a set of iterative statements that are used to execute a statement or a block of statements repeatedly as long as the given condition is true. The iterative statements are also known as looping statements or repetitive statements.
