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…
