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:The optimal method starts by arbitrarily putting the elements on a binary tree, respecting the shape property (the tree could be represented by an ar...
Officially, the time complexity of the algorithm for this article is said to be N operations, where N is the number of elements in the unordered array plus the dummy elements. In this case, N is 15. So the time complexity for this algorithm is 15. ...
3. Percolate Down on all non-leaf nodes The above arbitrary deletion algorithm takes O(n) time even if the location of the to-be deleted element is given. In fact, there is no need to percolate down on all non-leaf nodes. The following algorithm takes O(logn) time. 1. Swap the las...

respecting the shape property (the tree could be represented by an array, see below). Then starting from the lowest level and moving upwards, shift the root of each subtree downward as in the deletion algorithm until the heap property is restored. 时间复杂度是 O(N)., 参看上面链接里面build...
