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…

题目连接:2322 Wooden Sticks 题目大意:给出要求切的n个小木棍 , 每个小木棍有长度和重量,因为当要切的长度和重量分别大于前面一个的长度和重量的时候可以不用调整大木棍直接切割, 否则要进行调整.现在要求求出一个序列, 使得调整的次数最少, 输出调整的次数. 解题思路:将n个小木棍先按照 长度和重量的大小排序,然后按照顺序将小木棍分堆,可入堆的要求是长度和重量大于当前这个堆的长度和重量,入堆之后, 要将新的木棍的属性赋值个这个堆, 如果当前所有堆都没法放下这个木棍, 就得单独放成…
