题目链接 做题的时候凑的规律,其实可以 用式子推一下的. 题意:n对数,每对数有e,k, 按照题目的要求(可以看下面的Hint就明白了)求最小的值. 分析:假设现在总的是sum, 有两个e1 k1 e2 k2 则先选e1 为 (sum+e1)*k1+(sum+e1+e2)*k2 先e2: (sum+e2)*k2 + (sum+e1+e2)*k1. 比较两个式子发现不同的部分分别是 e1*k2   e2*k1; 比较大小移向 e1/k1  e2/k2, 那个小,就选那个,能达到最小. 官方题解:…

贪心 就跟NOIP2012国王游戏差不多,考虑交换相邻两题的位置,对其他题是毫无影响的,然后看两题顺序先后哪个更优.sort即可. WA了一次的原因:虽然ans开的是long long,但是在这一句:ans+=time*a[i].k;时,还是需要在time(int类型)前面加上(LL)进行类型强制转换. /************************************************************** Problem: 3850 User: ProgrammingAp…
