1 边界和湖心小岛分别算一个节点.连接全部距离小于D的鳄鱼.时间复杂度O(N2) 2 推断每一个连通图的节点中是否包括边界和湖心小岛,是则Yes否则No 3 冗长混乱的函数參数 #include <stdio.h> #include <malloc.h> #include <queue> #include <math.h> using namespace std; struct Coordinate { float x; float y; }; bool o…

其它pta数据结构编程题请参见:pta 题目 主要用到了深度优先搜索. #include <iostream> using namespace std; struct Vertex { int x; int y; bool marked; }G[]; int N; //总鳄鱼数 int D; //可以跳的距离 bool dfs(Vertex& v); bool firstJump(Vertex v); bool jump(Vertex v1, Vertex v2); bool succ…

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…

六度空间: “六度空间”理论又称作“六度分隔(Six Degrees of Separation)”理论.这个理论可以通俗地阐述为:“你和任何一个陌生人之间所间隔的人不会超过六个,也就是说,最多通过五个人你就能够认识任何一个陌生人.”如图1所示. “六度空间”理论虽然得到广泛的认同,并且正在得到越来越多的应用.但是数十年来,试图验证这个理论始终是许多社会学家努力追求的目标.然而由于历史的原因,这样的研究具有太大的局限性和困难.随着当代人的联络主要依赖于电话.短信.微信以及因特网上即时通信等工具,…
