其它pta数据结构编程题请参见:pta 题目 和简单版本不同的是,简单版本只需判断能否到达岸边,而这个版本要求求出最少跳数的路径. 简单版本用dfs实现,而这道题用BFS实现. 注意: 岛半径为7.5,而不是15.另外注意一步跳到岸边的情况. #include <iostream> #include <vector> #include <math.h> using namespace std; ; int N, D; struct point { int x, y; }…

题目来源: 浙江大学在慕课网上开设的<数据结构>课,陈越老师.何钦铭老师主讲,课后作业的一道题. 题目描述: 题目思路: 这道题目本质上讲就是列出图的连通集,但是这个连通集的起点是有约束的:詹姆斯邦德必须第一跳能跳到的点才是连通集的起点.解决这道问题可以使用DFS. C语言实现: 错误代码如下: //孤岛应该被作为单独一个节点来测试 //孤岛周围可能有很多鳄鱼,程序就是要考察这些鳄鱼(节点)的连通集 //里有没有可以跳到岸上的. #define _CRT_SECURE_NO_WARNINGS…

深度优先搜索(depth-first search)是对先序遍历(preorder traversal)的推广.”深度优先搜索“,顾名思义就是尽可能深的搜索一个图.想象你是身处一个迷宫的入口,迷宫中的路每一个拐点有一盏灯是亮着的,你的任务是将所有灯熄灭,按照DFS的做法如下: 1. 熄灭你当前所在的拐点的灯 2. 任选一条路向前(深处)走,每经过一个拐点将灯熄灭直到与之相邻的拐点的灯全部熄灭后,原路返回到某个拐点的相邻拐点灯是亮着的,走到灯亮的拐点,重复执行步骤1 3. 当所有灯熄灭时,结束 将…
