由以上过程可见,数组进行了log2(n)次二等分,排序过程每一层要进行 (n-1)次比较,因此算法复杂度为 nlog2(n) View Code 快速排序(QuickSort)整体上也可以分为 分组 和 排序 两部分,但没有归并排序那么规则,依然以上面的数组为例: 3,5,4,2,8,6,7,1 (以a[0]为基准,将数组分为两部分:比a[0]小的...
code voidmerge_sort(inta[],intl,intr){if(l>=r)return;intmid=l+r>>1;merge_sort(a,l,mid),merge_sort(a,mid+1,r);//分割成小块,开始归并intk=0,i=l,j=mid+1;while(i<=mid&&j<=r){if(a[i]<=a[j])tem[k++]=a[i++];elsetem[k++]=a[j++];}//归并结束,把另外一个数组街...

快速排序,和合并(merge)排序、堆排序,并称3大高级排序算法。 选择排序、冒泡排序、插入排序,并称3大low排序算法。 今天我们要介绍的是三大高级排序之一的,快速排序。 快速排序最大的特点,在于快。 而且,快…

systematicall review some sorting algorithms, including insertion sort, bubble sort, merge sort and quick sort. I then implement them in C++. All the function takes in avector<int>&type and directly operates on the input. To use the following code, you need to add the following code to ...
Selection Sort Insertion Sort Quick Sort Merge Sort The example code is in Java (version 1.8or higher will work). A sorting algorithm is an algorithm made up of a series of instructions that takes an array as input, performs specified operations on the array, sometimes called a list, and ...
