传送门:【HDU】1595 find the longest of the shortest 题目分析:首先求出一条最短路,记录下最短路上用到的边,枚举删除每一条边,求一次最短路,求完后恢复删除的边。重复这一过程直到枚举完所有的边为止。所有删除边后求得的最短路里最长的那条就是答案。 代码如下: #include <cstdio>#include <cstring>
Given a string S and a character C, return an array of integers representing the shortest distance from the character C in the string. Example 1: Input: S = "loveleetcode", C = 'e'Output: [3, 2, 1,

- The Shortest Path in Nya Graph 核心思想,将每一层建立俩个辅助点,如图,让该层的所有点与这两个点相连,边权分别为c与0,就成功地把建边的时间复杂度大大缩小了,如图 AC代码 #include<iostream>#include<queue>#include<string>#include<string.h>#include<algori
There is a path graph G=(V,E)G=(V,E) with nn vertices. Vertices are numbered from 11 to nnand there is an edge with unit length between ii and i+1i+1 (1≤i<n)(1≤i<n). To make the graph more interesting
By Stockholm 最短路计数(Shortest Path Count) 来源:Luogu P1144 题目描述 给出一个 N 个顶点 M 条边的无向无权图,顶点编号为 1~N。问从 顶点 1 开始,到其他每个点的最短路有几条。 输入输出格式 输入格式: 输入第一行包含 2 个正整数 N,M,为图的顶点数与边数。 接下来 M 行,每行两个正整数 x, y,表示有一条顶点 x
