WebJan 1, 2013 · Converting the heap to a BST in O (n) time, and Walking the BST in O (n) time to get a sorted sequence. Therefore, it is not possible to convert a heap to a BST in O (n) time (or in o (n log n) time, where o is little-o notation ). WebGiven two binary max heaps as arrays, merge the given heaps to form a new max heap. Example 1: Input : n = 4 m = 3 a[] = {10, 5, 6, 2}, b[] = {12, 7, 9} Output : {12, 10, 9, 2, 5, …

WebMay 1, 2024 · Let’s use the same array that we used to construct the min-heap to create the max-heap from an array. We start by adding the first node, 7. We move top-to-bottom, left-to-right and we add the 2nd node, 2. Since 7 is larger than 2, the nodes remain in their current position. Next, 9 is added to the heap. Since 9 is larger than 7, the two nodes ... tlv chemistry
