swap(a[i + 1],a[r]); return i + 1; } Figure below show how Partition works on an 8-element array. Array entry a[r] becomes the pivot element x. Lightly shaded array elements are all in the first partition with values no greater than x. Heavily shaded elements are in the second...

Quicksort是一种常用的排序算法,它在C++中的实现如下: 代码语言:cpp 复制 #include <iostream> using namespace std; // 交换两个元素的位置 void swap(int* a, int* b) { int t = *a; *a = *b; *b = t; } // 将数组分割为两部分,并返回分割点的索引 int partition(int arr[], int low,...
usingnamespacestd ; #defineEXCHAGE(X, Y) ((X) != (Y) ? (X) ^= (Y) ^= (X) ^= (Y) : NULL) intPartition(intarr[],intstart,intend) { inti=start-1, j=start ; for(;j<end ;++j) { if(arr[j]<=arr[end]) { //Swap two build-in type variable ++i ; EXCHAGE(arr[i],...
Quick Sort Algorithm with C++ Example: In this tutorial, we will learn about the quick sort algorithm and its implementation using the C++ program.
Quicksort has the O(nlogn) average time complexity, which is on par with the merge sort algorithm. Note, though, quicksort algorithm highly depends on the pivot selection method. In this case, we chose the naive version for choosing the pivot value, which was the first element in the vec...
