WebDec 18, 2016 · Normally you will use a max-heap for ascending sorting and a min-heap for descending sorting. This has to do with the way the heap sort algorithm is normally described: Build a max-heap with the original data. Now the maximal element is at the root of the tree, take this element at switch it with the last element of the tree. WebApr 23, 2024 · Design and Analysis of Algorithms Apr. 23, 2024 1.
