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…

# 函数原型detectMultiScale(gray, 1.2,3,CV_HAAR_SCALE_IMAGE,Size(30, 30)) # gray需要识别的图片 # 1.03:表示每次图像尺寸减小的比例 # 5:表示每一个目标至少要被检测到4次才算是真的目标(因为周围的像素和不同的窗口大小都可以检测到人脸) # CV_HAAR_SCALE_IMAGE表示不是缩放分类器来检测,而是缩放图像,Size(30, 30)为目标的最小最大尺寸…

题意: 输入两个正整数N和M(N<=500,M<=N^2),分别代表点数和边数.接着输入M行每行包括一条边的两个结点(0~N-1),这条路的长度和通过这条路所需要的时间.接着输入两个整数表示起点和终点,输出路径最短的路,如果多条路路径最短输出其中通过时间最短的路,以及通过时间最短的路,如果通过时间最短的路有多条输出其中经过点个数最短的路,如果两条路相同,则合并输出.详见样例. trick: 用邻接表存图,优先队列优化版本的dijkstra做,最后一个测试点会段错误,将数组开到25000以上后变…

题意:给了图,以及s和t,让你求s到t花费的最短路程.最短时间,以及输出对应的路径.   对于最短路程,如果路程一样,输出时间最少的. 对于最短时间,如果时间一样,输出节点数最少的.   如果最短路程和最短时间路径一样,合并输出一次即可. 纯粹就是练习dijkstra,没什么难的. 第一次dijkstra求最短路程,记录下每个节点的路程和时间. 第二次dijkstra求最短时间,记录下每个节点的时间和经过的节点数. pre数组用来存储前驱节点,保存路径 #include <iostream>…

题意:给定一个图,以及起点和终点,需要我们计算两条路径.第1条路径:距离最短路径,若不唯一,则选择用时最短的那一条:第2条路径:用时最少路径,若不唯一,选择经过结点数最少的那一条. 思路:两次Dijkstra即可.以往都是求一条路径,本题要求两条,没什么不同,只是代码量多了一些.编写代码前要心中有数,变量名怎么命名等等(变量名一多,命名真是件举棋不定的事..) 第1条路径:第1标尺为距离,第2标尺为用时,在Dijkstra中完成更新.用pre[v]记录结点v的前驱,在Dijkstra之后用DFS…
