C++數(shù)據(jù)結(jié)構(gòu)之實(shí)現(xiàn)鄰接表
本文實(shí)例為大家分享了C++數(shù)據(jù)結(jié)構(gòu)之實(shí)現(xiàn)鄰接表的具體代碼,供大家參考,具體內(nèi)容如下
一、圖的鄰接表實(shí)現(xiàn)
1.實(shí)現(xiàn)了以頂點(diǎn)順序表、邊鏈表為存儲(chǔ)結(jié)構(gòu)的鄰接表;
2.實(shí)現(xiàn)了圖的創(chuàng)建(有向/無向/圖/網(wǎng))、邊的增刪操作、深度優(yōu)先遞歸/非遞歸遍歷、廣度優(yōu)先遍歷的算法;
3.采用頂點(diǎn)對(duì)象列表、邊(?。?duì)象列表的方式,對(duì)圖的創(chuàng)建進(jìn)行初始化;引用 "ObjArrayList.h"頭文件,頭文件可參看之前博文“數(shù)據(jù)結(jié)構(gòu)之順序列表(支持對(duì)象元素)”代碼;
4.深度優(yōu)先遍歷分別采用遞歸/非遞歸算法;非遞歸中用到的棧,引用"LinkStack.h"頭文件,頭文件可參看之前博文“數(shù)據(jù)結(jié)構(gòu)之?!贝a;
5.廣度優(yōu)先遍歷采用隊(duì)列方式實(shí)現(xiàn);用到的隊(duì)列,引用 "LinkQueue.h"頭文件,頭文件可參看之前博文“數(shù)據(jù)結(jié)構(gòu)之隊(duì)列”代碼;
6.測(cè)試代碼中以有向網(wǎng)的所有帶權(quán)邊作為邊的初始化數(shù)據(jù),選擇圖類型(DG, UDG, DN, UDN)可創(chuàng)建成不同類型的圖。
7.優(yōu)劣分析:
7.1.(優(yōu)勢(shì))鄰接表存儲(chǔ)結(jié)構(gòu),相比鄰接矩陣,消除了無鄰接關(guān)系頂點(diǎn)的邊存儲(chǔ)空間;
7.2.(優(yōu)勢(shì))鄰接表比鄰接矩陣更容易訪問某頂點(diǎn)的鄰接頂點(diǎn);
7.3.(優(yōu)勢(shì))鄰接表比鄰接矩陣更易于統(tǒng)計(jì)邊總數(shù),無需逐行逐列遍歷;
7.4.(劣勢(shì))在確定兩頂點(diǎn)間是否有邊的搜索過程中,鄰接表不如鄰接矩陣可直接尋址快,反而需要頂點(diǎn)到邊鏈的遍歷;
7.5.(劣勢(shì))鄰接矩陣在刪除頂點(diǎn)時(shí),只需清除對(duì)應(yīng)行列數(shù)據(jù)即可;而鄰接表在清除頂點(diǎn)指向的邊鏈后,還需遍歷整個(gè)邊表,清除所有鄰接于此頂點(diǎn)的邊結(jié)點(diǎn);
7.6.(不足)鄰接表在統(tǒng)計(jì)有向圖出度時(shí)容易,只需遍歷依附此頂點(diǎn)的邊鏈;卻在統(tǒng)計(jì)其入度時(shí),需要遍歷整個(gè)邊表,比較麻煩;可采用十字鏈表(鄰接表與逆鄰接表的結(jié)合)解決這個(gè)問題;
7.7.(不足)鄰接表在無向圖的存儲(chǔ)中,屬于行列對(duì)稱矩陣形式,因此會(huì)有一半重復(fù)的邊數(shù)據(jù),故可采用鄰接多重表,只存儲(chǔ)一半邊,來優(yōu)化存儲(chǔ)。
二、測(cè)試代碼中的圖結(jié)構(gòu)

深度優(yōu)先遍歷序列(從 v1 頂點(diǎn)開始):
1.無向圖/網(wǎng):v1-v2-v3-v5-v4-v6-v7
2.有向圖/網(wǎng):v1-v2-v5-v3-v4-v6-v7
廣度優(yōu)先遍歷序列(從 v2 頂點(diǎn)開始):
1.無向圖/網(wǎng):v2-v1-v3-v5-v4-v6-v7
2.有向圖/網(wǎng):v2-v5 后序無法遍歷
注:有向圖的遍歷 是遵循出度方向遍歷的,若無出度方向,則遍歷終止。
