Heap sort is a comparison based sorting technique based on Binary Heap data structure. It is similar to selection sort where we first find the maximum element and place the maximum element at the end. We repeat the same process for remaining element. What is Binary Heap Let us first define a Complete Binary Tree. Zstr_count_x86_assembly.png' alt='Anagram Program In Java Source Code' title='Anagram Program In Java Source Code' />An anagram is word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the. A week or so ago I posted a piece called CodeKata, suggesting that as developers we need to spend more time just practicing writing throwaway code just to get the. The longest word is a part of the Countdown TV program, whose purpose is to find the longest word by using only some selected letters e. A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible Source WikipediaA Binary Heap is a Complete Binary Tree where items are stored in a special order such that value in a parent node is greateror smaller than the values in its two children nodes. The former is called as max heap and the latter is called min heap. The heap can be represented by binary tree or array. Why array based representation for Binary Heap Since a Binary Heap is a Complete Binary Tree, it can be easily represented as array and array based representation is space efficient. If the parent node is stored at index I, the left child can be calculated by 2 I 1 and right child by 2 I 2 assuming the indexing starts at 0. Heap Sort Algorithm for sorting in increasing order 1. Build a max heap from the input data. At this point, the largest item is stored at the root of the heap. Replace it with the last item of the heap followed by reducing the size of heap by 1. Finally, heapify the root of tree. Repeat above steps while size of heap is greater than 1. How to build the heapDownload the free trial version below to get started.

Heapify procedure can be applied to a node only if its children nodes are heapified. So the heapification must be performed in the bottom up order. Lets understand with the help of an example. Input data 4, 1. The numbers in bracket represent the indices in the array. Applying heapify procedure to index 1. Applying heapify procedure to index 0. The heapify procedure calls itself recursively to build heap. C program for implementation of Heap Sort. To heapify a subtree rooted with node i which is. Initialize largest as root.
