发一下牢骚和主题无关: 搜索,最短路都可以     每日一道理 人生是洁白的画纸,我们每个人就是手握各色笔的画师:人生也是一条看不到尽头的长路,我们每个人则是人生道路的远足者:人生还像是一块神奇的土地,我们每个人则是手握农具的耕耘者:但人生更像一本难懂的书,我们每个人则是孜孜不倦的读书郎. #include<stdio.h> #include<string.h> #include<queue> #define inf 0x3fffffff using namespace…

给你一个的棋盘, 问:从一个坐标到达另一个坐标需要多少步? 每次移动可以是八个方向.   #include <iostream> #include <cmath> #include <algorithm> #include <string> #include <cstring> #include <cstdio> #include <vector> #include <cstdlib> using namesp…

题意: 给你两个空瓶子,只有三种操作 一.把一个瓶子灌满 二.把一个瓶子清空 三.把一个瓶子里面的水灌到另一个瓶子里面去(倒满之后要是还存在水那就依然在那个瓶子里面,或者被灌的瓶子有可能没满) 思路:BFS,打印路径时需技巧. //G++ 840K 0MS #include <iostream> #include <cstdio> #include <cstring> #include <cstdlib> #include <stack> #in…

题目是给你起点sx,和终点gx:牛在起点可以进行下面两个操作: 步行:John花一分钟由任意点X移动到点X-1或点X+1. 瞬移:John花一分钟由任意点X移动到点2*X. 你要输出最短步数及打印路径. 最短步数用bfs就行了. 至于路径,用一个结构体就可以去存每个点的父节点,再递归输出路径就行了. #include<stdio.h>#include<algorithm>#include<string.h>#include<queue>using names…

标题效果: 鉴于国际棋盘两点,寻求同意的操作,是什么操作的最小数量,在操作过程中输出. 解题思路: 水题一个,见代码. 以下是代码: #include <set> #include <map> #include <queue> #include <math.h> #include <vector> #include <string> #include <stdio.h> #include <string.h>…

The king is left alone on the chessboard. In spite of this loneliness, he doesn't lose heart, because he has business of national importance. For example, he has to pay an official visit to square t. As the king is not in habit of wasting his time, h…

必须要抄袭一下这个代码 The king is left alone on the chessboard. In spite of this loneliness, he doesn't lose heart, because he has business of national importance. For example, he has to pay an official visit to square t. As the king is not in habit of wasting…
