题意是处理一批木棍,如果当前处理的木棍长度和重量均大于前一根木棍的长度和重量,则处理当前木棍花费为 0,否则花费为 1. 用结构体存储木棍信息,将木棍按照长度从小到大排序,若长度相等则按照重量从小到大排序,在序列中找到比当前所处理的木棍长度和重量均大于且未处理的木棍再进行处理,若没有满足要求的木棍了,则再次从头开始处理未处理过的木棍,直到所有的木棍处理完毕. 代码如下: #include <bits/stdc++.h> using namespace std; struct stick { i…

本题一看就知道是最长不减序列了,一想就以为是使用dp攻克了. 只是那是个错误的思路. 我就动了半天没动出来.然后看了看别人是能够使用dp的,只是那个比較难证明其正确性,而其速度也不快.故此并非非常好的解决方法. 所以我就直接硬算.硬模拟选择出非减子序列,选完就出答案了. 思路: 1 依照长度排序 2 依照不减原则选择重量,选一个,消灭一个. 最后消灭完了,就处理完成,答案就自然出来了. 原来是一道披着dp的外套的模拟题啊!一道伪装成难题的简单题. 代码也能够写的非常简洁: #include <s…
