Problem We have a grid with R rows and C columns in which every entry is either 0 or 1. We are going to perform N operations on the grid, each of which is one of the following: Operation M: Change a number in one cell of the grid to 0 or 1 Operation…

For example we have array of meeting objects: const data = [ { name: }, { name: }, { name: }, { name: }, { name: } ]; For a day, 8 hours, we want to take as any meetings as possible: ); You should write function 'optimizeMeetings', get the results of…

题意:给定一个N个点的零图,M次操作,添加或删除一条边,每一次操作以后,打印用1,2,...N/2条边构成的匹配数. 分析:因为N的范围很小,所以可以把点的枚举状态用二进制表示集合.用一维数组dp[S]表示二进制集合为S的点集的匹配数. 每次加边操作,从大到小遍历集合,dp[S]+=dp[S-u-v]:删边操作,从小到大遍历集合,dp[S]-=dp[S-u-v]. 预处理出每个1024之内每个数对应二进制含有1的个数,每次记录答案就将每个dp[S]加到ans[S对应的二进制个数]中. #incl…
