Bst to max heap leetcode
WebThe time complexity of the above solution is O(n), where n is the total number of nodes in the binary tree. The auxiliary space required by the program is O(h) for the call stack, where h is the height of the tree.. 2. Iterative Solution. The idea is to perform level order traversal for the given binary tree to check both structural and heap properties of a min-heap. WebMar 29, 2024 · It then converts the binary search tree into a min-heap using the 'BSTToMinHeaphelper' function. Now, convert the binary search tree into a min-heap using the 'MinHeap' function. Print the preorder traversal of the min-heap using the 'getPreorder' function. Dry Run. 1. First, create the BST using the ‘node()’ function. 2.

WebConvert a Binary Search Tree into a Min Heap Given a binary search tree (BST), efficiently convert it into a min-heap. In order words, convert a binary search tree into a complete binary tree where each node has a higher value than its parent’s value. WebKth Largest Element in an Array - Given an integer array nums and an integer k, return the kth largest element in the array. Note that it is the kth largest element in the sorted order, not the kth distinct element. You must solve it in O(n) time complexity. Input: nums = [3,2,1,5,6,4], k = 2 Output: 5 Example 2:
WebKth Smallest Element in a BST - Given the root of a binary search tree, and an integer k, return the kth smallest value (1-indexed) of all the values of the nodes in the tree.

WebMar 28, 2024 · By traversing the right subtree, we reach the largest element, and if it has a left subtree, the second largest element will be stored in the rightmost node of that subtree. The function starts by initializing two pointers, current and parent, to the root node of the BST and nullptr, respectively. The algorithm then enters a while loop, where ...
WebJan 1, 2013 · 1 Answer. There is no algorithm for building a BST from a heap in O (n) time. The reason for this is that given n elements, you can build a heap from them in O (n) time. If you have a BST for a set of values, you can sort them in O (n) time by doing an inorder traversal. If you could build a BST from a heap in O (n) time, you could then have an ... gata selvagem cap 63WebGiven the root of a binary tree, determine if it is a complete binary tree..
