从大到小遍历一遍,每次取M个元素,然后求得最小的floor即可 int minimum(int M, vector <int> heights) { sort(heights.begin(),heights.end()); int minFloor = 10000; for(int i = heights.size()-1; i >=M-1; -- i){ int floor = 0; for(int j = 0; j < M; ++j) floor +=heights[i]-he…

排个序,求前k个元素和即可 int minimum(int K, vector <int> danceCost) { sort(danceCost.begin(),danceCost.end()); return accumulate(danceCost.begin(),danceCost.begin()+K,0); }…

题目:http://community.topcoder.com/stat?c=problem_statement&pm=13204&rd=15857 这道题目须要用到博弈论中的经典理论,Sprague–Grundy theorem,以下将相关理论做一个总结: Impartial Game:公平游戏,两方除了谁先開始游戏外,其余都同样. Nim:一类经典的Impartial Game,非常多游戏都能够等价于Nim. Nimber(Grundy numbers):能够理解为标识一个游戏状态的…

SRM 623 DIV2 1000pt 题意:给出一个最多50*50的矩阵,每个单元可能为'.'.'P'.'A','.'代表空地,你每次操作可以把一个P或者A拿到空地上,求一个最大的含有相同字符的矩形面积,最多K次操作. 首先用一个数组预处理出所有矩形所包含这三种字符的数量,然后枚举每一个矩形,如果只含有相同字符,那么这个面积是可以取到的. 如果含有多种字符,枚举含哪种字符时所需操作最少,大矩阵内如果含有一个及以上空地并且这个矩形的面积是小于等于你当前枚举的字符的数量,操作数=矩形内空地数+令一…
