Mergesort是一种常见的排序算法,它采用分治的思想,将待排序的数组不断拆分为更小的子数组,然后再将这些子数组合并成有序的数组。以下是mergesort C实现的示例代码: 代码语言:c 复制 #include<stdio.h>// 合并两个有序数组voidmerge(intarr[],intleft,intmid,intright){inti,j,k;intn1=mid-left+1;intn2...

一、归并排序介绍将两个的有序数列合并成一个有序数列,我们称之为"归并"。 归并排序(Merge Sort)就是利用归并思想对数列进行排序。根据具体的实现,归并排序包括"从上往下"和"从下往上"2…
void mergesort(int a[], int first, int last, int temp[]) { if (first < last) { int mid = (first + last) / 2; mergesort(a, first, mid, temp); //左边有序 mergesort(a, mid + 1, last, temp); //右边有序 mergearray(a, first, mid, last, temp); //再将二个有序数列合...
Its only advantage over qsort is that it uses almost no additional memory; while qsort does not allocate memory, it is implemented using recursion. The function mergesort requires additional memory of size nmemb * size bytes; it should be used only when space is not at a premium. The ...

Using pointers on lists and mixing them (sort) can sometimes lead your code to suffer from high complexity will eventually can lead to bugs and errors. There tools who help to deal with those as checkmarx but it is recommended to make sure you code correctly and detect mistakes as you cod...
