Fat brother and Maze are playing a kind of special (hentai) game on an N*M board (N rows, M columns). At the beginning, each grid of this board is consisting of grass or just empty and then they start to fire all the grass. Firstly they choose two gr…

题意:就是选两个点出发,只能走草坪,看能不能走完所有的草坪 分析:由于数据范围很小,所有枚举这两个点,事先将所有的草坪点存起来,然后任选两个点走,(两个点可以是同一个点) 然后BFS就行了 注:无解的情况很好做,事先深搜判连通块的个数就好,大于2就无解(代码比较烂) #include<cstdio> #include<algorithm> #include<iostream> #include<cstring> #include<cmath> #…

传送门:点我 题意:“#”是草,"."是墙,询问能不能点燃俩地方,即点燃俩“#”,把所有的草烧完,如果可以,那么输出最小需要的时间,如果不行输出-1 思路:暴力BFS,看到n和m都不大,直接把每个“#”都存下来,每次加入2个点进广搜搜能否烧完,然后更新ans即可. #include <cstdio> #include <cstring> #include <cmath> #include <cstdlib> #include <ct…

题目: 两个熊孩子在n*m的平地上放火玩,#表示草,两个熊孩子分别选一个#格子点火,火可以向上向下向左向右在有草的格子蔓延,点火的地方时间为0,蔓延至下一格的时间依次加一.求烧完所有的草需要的最少时间.如不能烧完输出-1. 输入: 第一行,输入一个T,表示有T组测试数据. 每组数据由一个n,m分别表示行列 1 <= T <=100, 1 <= n <=10, 1 <= m <=10 输出: 输出最少需要的时间> 样例: 分析:双起点的BFS,本质上就是枚举两个起点…

在论文<SQUEEZENET: ALEXNET-LEVEL ACCURACY WITH 50X FEWER PARAMETERS AND <0.5MB MODEL SIZE>中,作者对模型进行压缩的核心我感觉就是利用许多的Fire Module模块来替代原来的conv+pool 其中所谓的"Fire Module"就是一种专门设计的结构,具体而言是由两部分构成:sequeeze以及后面连接的enpand两部分,其中的sequeeze部分是卷积核为1*1的卷积层,后面的…

Fire 分析: 首先,明确题意:b1,b2,--,bn 交换为b2,--,bn,b1,但这并不是意味着只能从b1开始交换,(这点从样例中可以看出),并且也不意味着交换的必须是连续的一串,可以是几个单点,如: 原序列:1 2 3 4 5,交换(1 3 5)后 新序列:3 2 5 4 1 交换时必须按照环的方式顺时针或逆时针转动,这并没有限制,只需要一个位置移动到另一个位置时将他顶替掉,他去找他自己应该到的位置就好了,最终是按一个环的移动方式移动,但不一定是从左到右或从右到左,方向交叉. 所以:…

题目大意:在一个N*M的迷宫内,J代表某人(只有一个),F代表火(可能不只一个),#代表墙,火每分钟会向四周除了墙以外的地方扩散一层,问人能否在没被火烧到 之前逃出迷宫,若能逃出输出最短时间.很明显的bfs.但由于火到达的地方人不能抵达,故需先对火进行bfs,标记后若人在火烧到之前抵达即可.最后逃出时间需要加一, 因为当时只是抵达边界,若逃出时间需加一. #include <stdio.h> #include <queue> #include <string.h> #i…

在上周Amazon也耐不住加入了手机竞争行列之中,发布了自己的Fire Phone,于是Android家族又多了一位变种成员,Android系统的碎片化程度也进一步加剧.因为工作的关系,我有幸在上个月就得到了一部工程机为其做提前开发,不过因为政策原因所以到现在才能来谈谈对这部新手机的看法. 对于Fire Phone的功能以及外观,官方网站和各家技术网站都有了详尽的介绍和报道,再者因为我拿到的是工程机,无法体现到完备的功能展现,因此本篇文章谈的主要是Fire Phone对于开发者而言所要面对的问题…

题目:Hire and Fire 题目翻译成数据结构就是:建树,加结点,删除结点,打印结点.只有删除结点稍微复杂点,因为删除设计掉树的调整. 首先要考虑树怎么存储才能使解题更顺手. 1.我们要存储每个结点的孩子,父亲和名字.存储孩子是因为第一个孩子可能会“升级”,存储父亲是因为要打印,名字肯定也是要打印的: 2.我们要知道每个结点的子树,删除结点会涉及调整: 3.我们要知道根节点,存放CEO. 所以我们的结点出来了,如下: struct Tman { string name; Tman *fat…
