决定在 codeforces 练题啦,决定每个比赛刷前四道...太难就算了 796A Buying A House 题意:给出x轴上的n 个点,每个点有个权值,问离m 点最近的权值小于等于k 的点离m的距离.单位是10. 思路:大水题.用l.r分别向左向右找即可. 代码: #include<stdio.h> int main(){ int n, m, k; ]; while(~scanf("%d%d%d", &n, &m, &k)){ ; i<…

[题目链接]:http://codeforces.com/contest/796/problem/B [题意] 一开始骨头在1号位置; 然后有m个洞,给出洞的下标; 然后有k个交换操作; 如果骨头到洞里了,就不能再交换了; 骨头就一直待在洞的下标位置; 问你k个操作后骨头在哪里 [题解] 用个一维数组模拟; 1代表骨头,0代表不是骨头; 然后开个map记录哪里是洞; 如果骨头到洞里面去了;就结束; 否则输出k次操作后1的下标就好了 [Number Of WA] 0 [完整代码] #include…

物联网(IoT)技术方兴未艾,智能手环,智能血压计,智能眼镜甚至智能鞋垫都开始进入我们的生活,各种智能设备层出不穷,世界已经到了一个"人有多大胆,地有多大产"的时代,不玩儿点物联网都不好意思和人打招呼了. 之前玩儿过开源硬件Arduino,这次再找个功能强劲的Beagle Bone Black(BBB). 大家可能知道名气更大的树莓派,BBB也是类似的单片计算机开发板,就在名片大小的一块板子上集成了计算机的大多数常见功能,在上面可以运行Linix 操作系统,通过HDMI连上显示器,插上…

题意:求解01背包价值的第K优解. 分析: 基本思想是将每个状态都表示成有序队列,将状态转移方程中的max/min转化成有序队列的合并. 首先看01背包求最优解的状态转移方程:\[dp\left[ j \right] = \max \left\{ {dp\left[ j \right],dp\left[ {j - a\left[ i \right].w} \right] + a\left[ i \right].v} \right\}\] 如果要求第K优解,那么状态 dp[j] 就应该是一个大小为…
