问题:最开始的思路是找到最小的部分,然后根据倍数计算,但是实在不知道怎么比较两个数的大小 答案:其实答案应该是对于每一个点i,i的成分大小应该是对于每一个其他点,比例中分母质数分解使每个质数最大时的乘积(因为需要能整除),但这样得到的结果是O(n^2),所以需要由一个点能直接推到多个点,其实(最大流,二分图的多重匹配) Magic Potion
题意:n个人,m个怪物,k瓶药水,每个人可以打死对应的集合里面的一个怪物,一碰药水可以让一个人多打死一个怪物,每个人最多只能用一瓶药水,问最多能打死多少个怪物思路:想到了匹配,然后用最大流做,一开始想的建图是从超级原点连一条容量是n+k的边到虚拟节点,然后虚拟节点与所有勇士连一条容量是Codeforces Round #723 (Div. 2)

题目链接 点我跳转 题目大意 给定 \(N\) 个物品和一个 \(X\) ,第 \(i\) 个物品的重量为 \(ai\),你可以从中选择任意个物品(不能不选) 假定选择了 \(S\) 个物品,物品的总重量为 \(V\) 那么再满足 \((X - V) \% S = 0\) 的前提下还需要支付 \((X - V) / S\) 的 \(money\) 问最少需要支
