题意: 众所周知lyb根本不学习.但是期末到了,平时不写作业的他现在有很多作业要做. CUC的老师很严格,每个老师都会给他一个DDL(deadline). 如果lyb在DDL后交作业,老师就会扣他的分. 现在假设lyb做作业都需要一天. 所以lyb想到要安排做作业的顺序,这样才能尽可能扣少一点分. 请帮帮bx吧. Input 输入包含T个测试用例.输入的第一行是单个整数T,为测试用例的数量. 每个测试用例以一个正整数N开头(1<=N<=1000),表示作业的数量. 然后两行.第一行包含N个整数…

给出点集,和不大于L长的绳子,问能包裹住的最多点数. 考虑每个点都作为左下角的起点跑一遍极角序求凸包,求的过程中用DP记录当前以j为当前末端为结束的的最小长度,其中一维作为背包的是凸包内侧点的数量.也就是 dp[j][k]代表当前链末端为j,其内部点包括边界数量为k的最小长度.这样最后得到的一定是最优的凸包. 然后就是要注意要dp[j][k]的值不能超过L,每跑一次凸包,求个最大的点数量就好了. 和DP结合的计算几何题,主要考虑DP怎么搞 /** @Date : 2017-09-27 17:27…
