The problem is in my percolate down algorithim, there is something I am not doing right. This isn't the typical "I wrote a heap sort that doesn't work, help me please" thread, instead, I'm one step before that. The ordering can be one of two types: the min-heap property: the value of each node is greater than or equal to the value of its parent, with the minimum-value element at the root. HeapSort in Java. There’s already a PriorityQueue class in the Java Core API. ) * * Heapsort uses two heap operations: insertion and root deletion. It is commonly assumed that Bubble-Sort is an extremely poor sort algorithm and gets really slow with larger number of input data. This layout makes it possible to rearrange heaps in place, so it is not. It is similar to selection sort where we first find the maximum element and place the maximum element at the end. MaxHeap(int capacity) Creates an empty MaxHeap with the given capacity. We can sort the array values using heap sorting algorithm. 4) Consider a priority queue with n items implemented by means of a heap the space used is O(n) methods insertItem and removeMin take O(log n) time methods size, isEmpty, minKey, and minElement take time O(1) time Using a heap-based priority queue, we can sort a sequence of n elements in O(n log n) time.
