题目分析: 意思是要求对于一个给出的数组,我们在其中尽可能多选数字,使得所选数字的max <= min * p,而由于数据量较大直接二层循环不加优化实现是不现实的,由题意得知,对于数字序列的子序列选择没有连续性要求,就是可以随便选的意思,所以我们先将整个序列从小到大排序(这样在遍历时j-i+1就是你选择的个数),从第i == 1个元素开始往后搜索,只要能满足max <= min * p就继续搜索,直到不满足的退出,而在i+1个元素开始搜索时我们发现,由于下标为i+1的元素一定比i大(从小到大排…

题意:N个数,M个询问,每个询问为一个区间,求区间最长连续子序列,要求每个数都不同(perfect sequence,简称PS). 题解:很容易求出以每个数为结尾的ps,也就是求区间的最大值.有一个不同就是长度可能会超出询问范围,所以先对PS的首位置二分,然后RMQ.注意一点,序列有可能出现负数,所以先加最大值变为正数.其实也不算变形,挺裸的…… 这题卡线段树,然而我只会线段树,心塞…… 代码(树状数组): #include <iostream> #include <cstring>…

一.概念 对于常用的数据结构,可分为线性结构和非线性结构,线性结构主要是线性表,非线性结构主要是数和图.当n>0时,表可表示为:(a0,a1,a2,a3,…an) 1. 线性表的特征: 1.存在唯一的被称作”第一个”的数据元素 2.存在唯一的一个称作”最后一个的”数据元素” 3.除第一个之外,集合中的每个数据元素均只有一个前驱 4.除最后一个之外,集合中每个元素均只有一个后继 2.线性表的基本操作 1.初始化: 2.返回线性表长度 3.获取指定索引处元素 4.按值查找元素位置 5.直接插入数据元…
