艺、 到解放生产力的工业产品、再到宇宙运行的科学规律，几乎每一件平凡或令人惊叹的事物背后，都隐藏着精 妙的算法思想。 同样，数据结构无处不在：大到社会网络，小到地铁线路，许多系统都可以建模为“图”；大到一个国家，小 到一个家庭，社会的主要组织形式呈现出“树”的特征；冬天的衣服就像“栈”，最先穿上的最后才能脱下； 羽毛球筒则如同“队列”，一端放入、另一端取出；字典就像一个“哈希表”，能够快速查找目标词条。 . . . . . . . . . . . . . . . . . 177 第 9 章 图 178 9.1 图 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 179 9.2 图的基础操作 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 183 9.3 图的遍历 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 188 9.4 小结 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
