Extract min/max. Question 2 After decreaseKey(), the minus infinite value must reach root, so we call extractMin() to remove the key. Duplicate zero’s without expanding the array. - a max-heap Priority queues may be used to manage prioritized processes in a time-sharing environment, time-dependent simulations, and even numerical . In a Min Binary Heap, the key at root must be minimum among all keys present in Binary Heap. Therefore the whole sorting algorithm has a runtime of O (n log n) Our heap can be represented with an array. A heap is a specialized tree-based data structure which is a complete binary tree that satisfies the heap property, that is, for each node all of it's children are in a relation to it. When all the levels up to the root of the whole tree have been processed, the structure is organized as a heap. Above tree is satisfying both Ordering property and Structural property according to the Max Heap data structure. IF new key is greater than its parent, then we don’t need to do anything. i have 5 cases here and i managed to trace out the first 3 out of the 5 cases. Max Heap. A leftist heap is a modification priority queue implemented with variant of binary heap.
