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…
归并排序(Merge-Sort)的C语言实现 归并排序是分治法(Divide-and-Conquer)的典型应用: Divide the problem into a number of subproblems. Conquer the subproblems by solving them recursively. if the subproblem sizes are small enough, just sovle the subproblems in a straightforward manner. Combine the ...
merge()是C++标准库的函数，主要实现函数的排序和合并，不仅仅是合并，具体要求参照标准库。include"stdafx.h"include<iostream> include<algorithm> include<array> include<list> usingnamespacestd;boolcomp(constinti,constintj){ returni>j;} intmain(void){ /*自定义谓词*/ std::array<int,4>...
