MaxHeapify Aheapis a specializedtree-baseddata structurethat satisfies theheap property:IfAis a parentnodeofBthen key(A) is ordered with respect to key(B) with the same ordering applying across the heap. Either the keys of parent nodes are always greater than or equal to those of the childre...
将8保存给变量ans,然后交换8和6(最后一个结点),然后heapSize--,将8逻辑删除。最后对堆顶元素6进行heapify,使heapify后的数组保持堆特性。 // 返回最大值publicintpop(){intans=heap[0];swap(heap,0,--heapSize);heapify(heap,0,heapSize);returnans;} 堆顶的6与自己的左右孩子PK(因为左孩子下标为1小于...
algorithm MaxHeapify(B, s): // INPUT // B = input array // s = an index of the node // OUTPUT // The heap tree that obeys max-heap property left <- 2 * s right <- 2 * s + 1 if left <= B.length and B[left] > B[s]: largest <- left else: largest <- s if righ...

Thus, heapify needs to check if the current element can be included in the Max Heap structure as-is or if it needs to be swapped with its children until it finds its correct place. The pseudocode for heapify is given below: algorithm HEAPIFY(A): // INPUT // A = an array to heapify...
