Wooden Sticks 点我挑战题目 题意分析 给出T组数据,每组数据有n对数,分别代表每个木棍的长度l和重量w.第一个木棍加工需要1min的准备准备时间,对于刚刚经加工过的木棍,如果接下来的木棍l和w均小于等于上一根木棍的l和w那么就不许要准备时间,否则的话还需要1min的准备时间.求解对于每组数据,所需要的最小的准备时间是多少. 贪心策略. 对木棍进行降序排序,首要关键字是l,次要关键字是w(可以颠倒).然后选取最顶端的木棍,向下遍历,对于当前木棍,若l和w均小于等于顶层木棍,那么标记它…

题意:给出n个木头的重量wi,长度li,如果满足w[i+1]>=w[i]且l[i+1]>=l[i],则不用耗费另外的加工时间,问至少需要多长时间加工完这些木头. 第一次做这一题目也没有做出来---而且也是好久以前---于是又看题解了--- 发现和将木材按两个关键字(先按重量由大到小排,如果重量相等的话则按长度由大到小排)排序后,和导弹拦截系统是一样的了,求长度的最长上升子序列. 自己写的二分查找一直输不出结果----555555 后来用了题解里面的lower_bound函数 搜了一点lower…
