Web13 de mar. de 2024 · Heapsort is an in-place sorting algorithm with worst case and average complexity of O (n logn). The basic idea is to turn the array into a binary heap structure, which has the property that it allows efficient retrieval and removal of the maximal element. WebIn first Example, first we have to build Max Heap. So, we will start from 20 as child and check for its parent. Here 10 is smaller, so we will swap these two. Now, child 17 is greater than its parent 10. So, both will be swapped and order will be 20 17 15 10 9 21. Now, child 21 is greater than parent 15. lymphe borreliose
