归并排序(MERGE-SORT)是建立在归并操作上的一种有效的排序算法,该算法是采用分治法(Divide andConquer)的一个非常典型的应用。将已有序的子序列合并,得到完全有序的序列;即先使每个子序列有序,再使子序列段间有序。若将两个有序表合并成一个有序表,称为二路归并。 归并排序核心步骤: 归并排序的步骤如下: 将待排序序列分为两个子序列,
}// 释放动态分配的内存free(L);free(R); }// 递归实现归并排序voidmergeSort(intarr[],intleft,intright){if(left < right) {intmid = left + (right - left) /2;// 递归排序两个子数组mergeSort(arr, left, mid); mergeSort(arr, mid +1, right);// 合并两个子数组merge(arr, left, mid,...
void MergeSort(int arr[], int p, int r); void Merge(int arr[], int p, int q, int r); int _tmain(int argc, _TCHAR* argv[]) { int original[] = {6,4,3,1,7,5,2}; PrintArray(original); PrintNewLine(); MergeSort(original,0,SIZE - 1); PrintArray(original); PrintNewLine...
void merge_sort(int A[],int p,int r) { int q; if(p<r) { /*q=(int)((p+r)/2); 下取整可用floor(),上取整可用ceil(),包含在math.h中*/ q=floor((float)(p+r)/2.0); merge_sort(A,p,q); merge_sort(A,q+1,r); merge(A,p,q,r); } } /* void main() { int a[10]...
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...
时间复杂度为O(n),而时间复杂度为O(n. log(n)),因此,在任何情况下,MergeSort的时间复杂...
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…
The mergesort function behaves similarly, but requires that size be greater than "sizeof(void *) / 2". The contents of the array base are sorted in ascending order according to a comparison function pointed to by compar, which requires two arguments pointing to the objects being compared. ...
