现在我们用 BUILD-MAX-HEAP 算法对数组 A=(5,3,17,10,84,19,6,22,9) 进行操作。1.首先，将数组 A 中的第一个元素 5 作为堆顶元素。2.然后，依次将数组 A 中的其他元素加入堆中，按照最大堆的性质进行调整。3.添加 3 到堆中，由于 3 比堆顶元素 5 小，所以将 3 放在堆底。4.添加 17 到堆中...
Is it possible to build a max heap from two heap without rebuilding the heap? I recently took my Computer Science exam and there was a question like that. There are two max-heaps (array implemented). You need to come up with an algorithm that merges these two max-...
是一种用于构建最大堆的算法。最大堆是一种特殊的二叉树结构,其中每个节点的值都大于或等于其子节点的值。buildMaxHeap方法的目标是将一个无序的数组转换为最大堆。 算法步骤如下: 1. 从数组的...
int buf [ARRAY_SIZE]; int n; max_heap(int x) { int l=2*x,r=l+1,large=x; if(l<=n&&buf[l]>buf[x])large=l; if(r<=n&&buf[r]>buf[x])large=r; if(large!=x) { int tmp=buf[large];buf[large]=buf[x];buf[x]=tmp; max_heap(large);//recurrence adjust } } int main...
在 BUILD-MAX-HEAP 的第 2 行中，我们使用循环控制变量 i 从 A.length/2 到 1 递减，而不是从 1 到 A.length/2 递增，这是因为我们希望每次将当前节点的较大孩子与它的兄弟节点进行比较，从而确保堆的性质。在构建最大堆的过程中，我们希望每个节点都能够与其较大的孩子进行比较，以保证当前节点比其孩子...
Yep, it's a valid case because you need to keep your max/min element at the top (depending on whether it's a max heap or a min heap). Heapify is not: creating a heap from an array which is a bottom-up operation with a time complexity of O(n) You're right, it's not. As ...
