The example sorts an array of integers in descending order. $ ./heap_sort_desc.py Sorted array in descending order: [13, 12, 11, 7, 6, 5] Heap Sort vs Quick SortHeap sort and quick sort are both efficient sorting algorithms. Heap sort has a guaranteed time complexity of O(n log ...
Median is the number that in the middle of a sorted array. If there are n numbers in a sorted array A, the median is A[(n – 1) / 2]. For example, if A=[1,2,3], median is 2. If A=[1,19], median is 1. Example For numbers coming list: [1, 2, 3, 4, 5], return...

We want to get K = 3 smallest items from the array and using Max heap data structure. So this is how to think about it. 1. We take first K items put it into Max Heap: 5 / \ 4 1 2. Then we move forward to next element '2' in the array, we check Whether 2 is smaller th...
Heapsortoperates by forming a heap, extracting the min/max item and repeating on the smaller array until everything is sorted. This can be done in-place by first building a heap and then incrementing the start index of the array. Heapsort runs inO(nlogn)O(n \log n)O(nlogn)time. Th...
is sorted by memory addresses in ascending order. When an allocation request comesin, the allocator looks for the first free block of memory that is large enoughto hold the requested size plus any metadata (like bookkeeping information, i.e., the size of the memory block). Scc...
I wonder if it's possible to do better than min-max heap by forgoing min-max property? Ie, an array can pack three interleaving tetrary max heaps.This give you the same parallel comparisons + four consequtive chilren in a row property. ...

The comparator passed to Priority Queue is sorted in descending order of String length. Note: Problems that are doable using Priority Queue are those where we are asked to "find the highest / lowest K values". 3. Given an array of points where points[i] = [xi, yi] represents a point...
(1). It may be accomplished using an array and requires no additional space for the pointer.Disadvantages:Printing all heap members in sorted order requires O(N*log N) time complexity, while BST merely requires O(N) time. Globally used heap memory makes memory management more complicated. ...
