【贪心】cf1144G. Two Merged Sequences

题目分析

打算去cf写写大致题解:

There might be another greedy algorithm using LIS/LDS which is more easier to make sense(it doesn‘t need swapping):

To the first element $a_1$,it belongs to the increasing/decreasing sequence.Let‘s only consider it‘s in the increasing sequence,for the other situation is just the same.

Codeforces #550 (Div3) - G.Two Merged Sequences(dp / 贪心)

Problem  Codeforces #550 (Div3) - G.Two Merged Sequences Time Limit: 2000 mSec Problem Description Two integer sequences existed initially, one of them was strictly increasing, and another one — strictly decreasing. Strictly increasing sequence is a

Codeforces 1144G Two Merged Sequences dp

Two Merged Sequences 感觉是个垃圾题啊, 为什么过的人这么少.. dp[ i ][ 0 ]表示处理完前 i 个, 第 i 个是递增序列序列里的元素,递减序列的最大值. dp[ i ][ 1 ]表示处理完前 i 个, 第 i 个是递减序列序列里的元素,递增序列的最小值. 然后随便转移转移顺便记录一下路径就好啦. #include<bits/stdc++.h> #define LL long long #define fi first #define se second #de

Codeforces 798D Mike and distribution - 贪心

Mike has always been thinking about the harshness of social inequality. He's so obsessed with it that sometimes it even affects him while solving problems. At the moment, Mike has two sequences of positive integers A = [a1, a2, ..., an] and B = [b1, 

Codeforces Round #243 (Div. 1)——Sereja and Two Sequences

题目链接 题意:给两个长度分别为n和m的序列,现在有两种操作:1.分别选择两个序列的一个非空前缀,切两个前缀的最后一位相同,删除之,得到1分(只累计),消耗e:2.直接删除两个序列,消耗值定于两个序列之前删除的元素个数之和,并且使得得到的分有效(之前没有有效分) 分析: 首先,问题其实就是转化成,进行若干次操作1,然后进行操作2 还要找到一个判别标准,来评判较优的状态(贪心) 每次的消耗值比较大,其实可以计算出最大的删除次数,这个值不是很大 状态表示: 简单的,一个状态可以表示为串A的位置.串B

[LeetCode]Repeated DNA Sequences

题目:Repeated DNA Sequences 给定包含A.C.G.T四个字符的字符串找出其中十个字符的重复子串. 思路: 首先,string中只有ACGT四个字符,因此可以将string看成是1,3,7,20这三个数字的组合串: 并且可以发现{ACGT}%5={1,3,2,0};于是可以用两个位就能表示上面的四个字符: 同时,一个子序列有10个字符,一共需要20bit,即int型数据类型就能表示一个子序列: 这样可以使用计数排序的思想来统计重复子序列: 这个思路时间复杂度只有O(n),但是

【uva 1615】Highway(算法效率--贪心 区间选点问题)

题意:给定平面上N个点和一个值D,要求在x轴上选出尽量少的点,使得对于给定的每个店,都有一个选出的点离它的欧几里德距离不超过D. 解法:先把问题转换成模型,把对平面的点满足条件的点在x轴的直线上可得到一个个区间,这样就是选最小的点覆盖所有的区间的问题了.我之前的一篇博文有较详细的解释:关于贪心算法的经典问题(算法效率 or 动态规划).代码实现我先空着.挖坑~
