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>a...
Merge(2,2,3) => 4 6 1 3 7 5 2 Merge(0,1,3) => 1 3 4 6 7 5 2 Merge(4,4,5) => 1 3 4 6 5 7 2 Merge(4,5,6) => 1 3 4 6 2 5 7 Merge(0,3,6) => 1 2 3 4 5 6 7 1 2 3 4 5 6 7 递归排序的算法复杂度为:O(nlgn)。 分类: Programming, Algorithm 标...
一、算法的概念 (1)算法(Algorithm) 是将一组输入转化成一组输出的一系列计算步骤,其中每个步骤必须能在有限时间内完成。 (2) 二、插入排序 1.用玩扑克的方式解释插入排序 要点在于: (1)前提:每次插入新的值时,前面的序列都是有序的 (2)但和插入扑克牌有一点不同,不可能在两个相邻的存储单元之间再插入一...

MergeSort(A, p, r): if p > r return q = (p+r)/2 mergeSort(A, p, q) mergeSort(A, q+1, r) merge(A, p, q, r) To sort an entire array, we need to call MergeSort(A, 0, length(A)-1). As shown in the image below, the merge sort algorithm recursively divides the ...
The mergesort algorithm is stable. The qsort and qsort_r functions are an implementation of C.A.R. Hoare's "quicksort" algorithm, a variant of partition-exchange sorting; in particular, see D.E. Knuth's "Algorithm Q". Quicksort takes average time. This implementation uses median ...
从逻辑层次来看,在STL中体现了泛型化程序设计的思想,引入了诸多新的名词,比如像需求(requirements),概念(concept),模型(model),容器(container),算法(algorithmn),迭代子(iterator)等。与OOP(object-oriented programming)中的多态(polymorphism)一样,泛型也是一种软件的复用技术;从实现层次看,整个STL是以一种类型参数...
