题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805347523346432 题意: 告诉你一个地铁线路图,站点都是用四位数来编号. 现在问你从某一起点到某一终点,经过站数最少的乘车方式是什么?要输出方案. 如果站数相同要输出换乘较少的. 思路: 首先肯定是搜索没有问题了.因为要输出方案,所以bfs不太方便存答案.很容易想到用dfs 比较麻烦的是输出方案的时候,线路相同的那些站都合并在同一个线路里了.那么我们就再

最短路. 记录一下到某个点,最后是哪辆车乘到的最短距离.换乘次数以及从哪个位置推过来的,可以开$map$记录一下. #include<map> #include<set> #include<ctime> #include<cmath> #include<queue> #include<string> #include<stack> #include<vector> #include<cstdio>

题意:给出起点和终点,计算求出最短路径(最短路径即所经过的站点最少的),若最短路径不唯一,则选择其中换乘次数最少的一条线路. 思路:本题虽然也是求最短路径,但是此路径是不带权值的,路径长度即所经过的边数,故可以用DFS来求解,而不是用一般的Dijkstra之类的.相信若只是求最短路径,大多数人都会做,就是从起点start开始深度遍历,遍历到终点end时,与全局变量进行比较.更新.本题的关键是,更新最优路径时需要比较“换乘次数”,如何求解它呢?我是这么思考的——首先,考虑用一个二维数组int mp

dfs,选择最优路径并输出~ 这道题难度非常炸裂,要求完完整整自己推一遍,DFS才算过关!思路:一遍dfs,过程中要维护两个变量,minCnt 中途停靠最少的站.minTransfer需要换成的最少次数1 可以这样算出一条线路的换乘次数:在line数组里保存每两个相邻站中间的线路是几号线,从头到尾遍历最终保存的路径,preLine为前一小段线路编号,如果当前的节点和前一个节点组成的这条路的编号和preLine不同,说明有一个换乘,就将cnt+1,最后遍历完累加的cnt即是换乘的次数.2 line
