#STL中<algorithm>文件中包含的常用函数 ###一、非修改性序列操作(12个) 功能 函数 循环对序列中的每个元素执行某操作 for_each() 查找在序列中找出某个值的第一次出现的位置 find() 在序列中找出符合某谓词的第一个元素 find_if() 在序列中找出一子
void heap_sort(int arr[], int len) { //初始化,i從最後一個父節點開始調整 for (int i = len / 2 - 1; i >= 0; i--) max_heapify(arr, i, len - 1); //先將第一個元素和已经排好的元素前一位做交換,再從新調整(刚调整的元素之前的元素),直到排序完畢 ...

push_heap: 将一个元素push进由序列表示的heap中,并维持堆得性质。 pop_heap: 将一个元素从heap中pop(实际上被交换到尾部)。 make_heap: 将给定序列构造成heap。 sort_heap: 对给定堆进行排序(可能有特殊的算法对堆排序进行优化)。 is_heap、is_heap_util: 判断给定序列是否为堆、判断给定序列到哪个位置之前...
C# – Heap Sort Algorithm Posted on June 21, 2015 by Vitosh Posted in C Sharp Tricks The last week I was fighting with algorithms again. Thus, I had to implement the mighty heap sort in C# and here is what I came up with. The idea of the code below is the following: In line...
The following example demonstrates heap sort in Python for numeric data. heap_sort.py #!/usr/bin/python def heapify(arr, n, i): largest = i left = 2 * i + 1 right = 2 * i + 2 if left < n and arr[i] < arr[left]: largest = left if right < n and arr[largest] < arr...

This is the runtime when everything in the input is identical. Since we cleverly reused available space at the end of the input list to store the item we removed, we only need O(1)O(1) space overall for heapsort. Share Tweet Share Interview coming up? Get the free 7-day email...
