下面给出Heap的 Summary, 转来的:implemented a Heap class that can specify min heap or max heap with insert, delete root and build heap functions. Time Complexity分析:Binary Heap Insert: O(logN), Delete: O(logN), Search: O(N), Space: O(N), Build本来应该O(NlogN), 但是如果用巧妙办法:...
Also worth mentioning, that 50% of the elements are leaves, and 75% of elements are at the two bottommost levels. Therefore, most insert operations won’t take more, than two steps. Note, that on real-world data, Quicksort is usually more performant than Heap Sort. The silver lining is...

Because of heapify() , the time complexity of this method is O(logn) . heapify() :This will be the private method for the MaxHeap class . The method ensures that heap property is maintained . insert() :The method is used to insert new nodes in the max heap . A new node is inser...
If 𝑛<3𝑘n<3k, and no phase is under way, proceed by brute force: For Insert, add the new element to the list; for Delete i, compute the elements in the ith quantile group and delete (return) one of them arbitrarily. Since k is constant, each operation takes time 𝑂(3𝑘)...
Delete Deletes a node given a reference to the node Θ(\log n) Extract minimum Removes and returns the minimum value given a reference to the node Θ(\log n) Find minimum Returns the minimum value O(\log n)* Insert Inserts a new value O(\log n) Union Combine the heap with another...
