WebDoing a heap sort is going to be three steps. The first step is we want to build a heap, and to build a heap we can do this operation in simply O of n time to create a heap out of a list of elements. The next thing we need to do to actually get at the sorted lists in our heap sort, we need to call n calls of removeMin. So, once we've built the ...

WebWe see that the worst case of Max-Heapify occurs when we start at the root of a heap and recurse all the way to a leaf. We also see that Max-Heapify makes a choice of recursing to its left subtree or its right subtree. When Max-Heapify recurses it cuts the work down by some fraction of the work it had before. WebExercise: BuildHeap. A heap can be built from a table of random keys by using a linear time bottom-up algorithm (a.k.a., Build-Heap, Fixheap, and Bottom-Up Heap Construction). This algorithm ensures that the heap-order property (the key at each node is lower than or equal to the keys at its children) is not violated in any node.
