PAT甲级1131. Subway Map 题意: 在大城市,地铁系统对访客总是看起来很复杂.给你一些感觉,下图显示了北京地铁的地图.现在你应该帮助人们掌握你的电脑技能!鉴于您的用户的起始位置,您的任务是找到他/她目的地的最快方式. 输入规格: 每个输入文件包含一个测试用例.对于每种情况,第一行包含正整数N(<= 100),地铁线数.然后N行跟随,第i(i = 1,...,N)行以格式描述第i条地铁线: M S [1] S [2] ... S [M] 其中M(<= 100)是停止次数,S [i…

PAT甲级1127. ZigZagging on a Tree 题意: 假设二叉树中的所有键都是不同的正整数.一个唯一的二叉树可以通过给定的一对后序和顺序遍历序列来确定.这是一个简单的标准程序,可以按顺序打印数字.但是,如果您认为问题太简单,那么您太天真了. 这次你应该以"锯齿形顺序"打印数字 - 也就是说,从根开始,逐级打印数字,从左到右交替,从右到左.例如,对于以下树,您必须输出:1 11 5 8 17 12 20 15. 输入规格: 每个输入文件包含一个测试用例.对于每种情况,第…

PAT甲级1123. Is It a Complete AVL Tree 题意: 在AVL树中,任何节点的两个子树的高度最多有一个;如果在任何时候它们不同于一个,则重新平衡来恢复此属性.图1-4说明了旋转规则. 现在给出一系列插入, 您应该输出生成的AVL树的级别遍历序列,并告知它是否是完整的二叉树. 输入规格: 每个输入文件包含一个测试用例.对于每种情况,第一行包含正整数N(<= 20). 一行中的所有数字都以空格分隔. 输出规格: 对于每个测试用例,将键逐个插入到初始空的AVL树中.然后首先…

PAT甲级1119. Pre- and Post-order Traversals 题意: 假设二叉树中的所有键都是不同的正整数.一个唯一的二进制树可以通过给定的一对后序和顺序遍历序列来确定,也可以通过预序和顺序遍历序列来确定.然而,如果仅给出了后序和预序遍历序列,则相应的树可能不再是唯一的. 现在给出一对postorder和preorder遍历序列,你应该输出树的相应的顺序遍历序列.如果树不是唯一的,只需输出任何一个树. 输入规格: 每个输入文件包含一个测试用例.对于每种情况,第一行给出正整数…

PAT甲级1114. Family Property 题意: 这一次,你应该帮我们收集家族财产的数据.鉴于每个人的家庭成员和他/她自己的名字的房地产(房产)信息,我们需要知道每个家庭的规模,以及他们的房地产的平均面积和数量. 输入规格: 每个输入文件包含一个测试用例.对于每种情况, 第一行给出正整数N(<= 1000).然后N行跟随,每个给出一个拥有庄园的人的信息,格式如下: ID父亲母亲k Child1 ... Childk M_estate Area 其中ID是每个人唯一的4位数识别号码;父…

PAT甲级1111. Online Map 题意: 输入我们当前的位置和目的地,一个在线地图可以推荐几条路径.现在你的工作是向你的用户推荐两条路径:一条是最短的,另一条是最快的.确保任何请求存在路径. 输入规格: 每个输入文件包含一个测试用例.对于每种情况, 第一行给出两个正整数N(2 <= N <= 500),M分别是地图上街道交叉路口的总数和街道数.然后M行跟随,每个描述一个街道的格式: V1 V2单程长度时间 其中V1和V2是街道两端的索引(从0到N-1);一- 方式是1,如果街道从V1…
