pid=5045">主题链接~~> 做题感悟:比赛时这题后来才写的,有点小尴尬.两个人商议着写写了非常久才写出来,I want to Powerful ,I believe me . 解题思路: 遗憾 ! 感觉领悟能力太低 .由于随意时刻随意两个人做的题不超过 1 题 ,so~>  必须是一轮一轮的来(n 道题一轮),每一个人在一轮中仅仅能做一题.假设多做一题就,有可能某个人没选,某个人选择了两道,这样就不符合规定了 . 用 1  代表选择.0  代表没选择.进行某一行的时候就…

一道极其水的拓扑排序……但是我还是要把它发出来,原因很简单,连错12次…… 题意也很裸,前面的废话不用看,直接看输入 输入n, m表示从0到n-1共n个人,有m组关系 截下来m组,每组输入a, b表示a指向b,或者b指向a也行. 输入n == 0时结束 如果可以拓扑排序,输出"YES",否则输出"NO".每组输出占一行. 给两种代码吧,一种用邻接矩阵,另一种我也不知道叫什么好…… 邻接矩阵—— #include <cstdio> #include <…

题解:我们使用一个二位数组dp[i][j]记录进行到第i个任务时,人组合为j时的最大和(这里的j我们用二进制的每位相应一个人). 详细见代码: #include <iostream> #include <cstdio> #include <cstring> #include <cmath> using namespace std; typedef long long ll; double s[11][1010]; double dp[1010][1050];…

题意: n和人做m道题, 每俩人做的题数不能相差一题以上.(也就是每n道题分别由n个人完成)   给n个人分别做m道题的概率, 求完成m题的最大期望 $1\le N \le 10$ 注意!!! fill dp 的地方!  [0, m]  所以要 m+1 !! #include <cstdio> #include <cstdlib> #include <cstring> #include <climits> #include <cctype> #i…

因为是circle sequence,可以在序列最后+序列前n项(或前k项);利用前缀和思想,预处理出前i个数的和为sum[i],则i~j的和就为sum[j]-sum[i-1],对于每个j,取最小的sum[i-1],这就转成一道单调队列了,维护k个数的最小值. ---------------------------------------------------------------------------------- #include<cstdio> #include<deque&…
