Making the Grade(POJ-3666)

题目大意是给出一个长度为 n 的序列,要求使序列变为单调上升或单调不减序列(非严格),问花费的最少代价? 转移方程是:dp[i][j]表示前i个元素的最后一个元素为全部元素第j小时的最小代价 #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<cmath>

POJ3666 - Making the Grade - 简单DP+滚动数组

题意 先给出了一个\(n\),之后给出\(n\)个数, 要求通过改变一些数,使得最后变成有序的序列(增或减),输出最小的修改量。 思路 二维DP+滚动数组。 因为数据较弱,所以不用严格递增或严格递减,所以序列中的高度一定是出现过的高度。 所以,最终修改后,或者和前一个数字一样,或者和后一个数字一样,这

CDOJ-65 CD Making

链接 https://acm.uestc.edu.cn/problem/cd-making/description 依据k分两种情况:k<=13时不用解释; k>13时,若n整除k,k除n即为答案,若不能整除,要注意n%k=13的情况,此时若k>=15,则只需多取一张CD来存放剩余歌曲,例如k=15,n=43,此时一种放法为(15,14,14)而不是(15,15,12,1)。但若k=14则需多取两张CD

POJ3336 Making the Grade

思路:DP 提交:1次 题解: 最开始我们可以想到,分两种序列都做一遍。 先来证明一个结论: 存在一种构造,使 \(B\) 中的数都在 \(A\) 中出现过,且这样不劣。 (目的是为了转化暂时看起来虚无缥缈的DP) 显然一个数成立,考虑 \(B\) 的前 \(k-1\) 项,向后插入一个数 \(B_k\)。 若 \(B_{k-1}\leq A_k

Making the Grade

POJ 题意:给定一个N\((N<=2000)\)个数的序列\(a_i\),构建一个非严格单调的序列\(b_i\),使得\(|a_1-b_1|+|a_2-b_2|+...+| a_N-b_N|\)的值最小. 分析:首先一看到这题,应该就会有一种直觉----序列b中的数全都来自于序列a. 证明:数学归纳法.\(N=1\)时显然满足条件. 假设N=i-1满足条件,
