一开始没多想,虽然注意到数据N<=10^4的范围,想PAT的应该不会超时吧,就理所当然地用dfs做了,结果最后一组真的超时了.剪枝啥的还是过不了,就意识到肯定不是用dfs做了.直到看到别人说用01背包的思路,果真好久没做题了智力水平下降,且原本dp就是我的弱项,压根就没把这题往dp上去想额... (http://www.liuchuo.net/archives/2323) 题意:从n个硬皮中选取方案,使得总和价值正好为m,如果有多种,方案为排列最小的那个. 可以把硬币看成w=v(即容量=价值)的…

题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805402305150976 题意: n个硬币,每一个有一个特有的价值,一个硬币只有一个,要求选取一些硬币使得他们的价值刚好是m 输出字典序最小的方案. 思路: 最近好久没有刷题了连PAT都好久没动了这样不行啊.连背包都有点不大会了.赶紧把PAT30分的刷完去刷洛谷了. 硬币是一个weight和value相同的物品,背包的容量就是m 问题转换成尽量让包中的价值大,背…

满背包问题,把体积和价值看成相等的.用滚动数组优化,然后额外开辟一个choice数组来记录每次的选择,然后回溯打印.因为要按字典序,先把价值进行排序.假如选最小的商品能装满m的话,那就把判断条件改成大于等于,然后最后来 #include<bits/stdc++.h> using namespace std; ]; ]; ]; ][]; int n, m; bool cmp(int a, int b) { return a > b; } int main() { memset(flag,…

这次的题目来源是 2013 年 10 月 7 日下午的浙大计算机研究生招生机试题. 这次题目的难度,按姥姥的说法是:『比普通的 PAT 要难了 0.5 个点.我是把自己的题目从 1.0 到 5.0 以 0.5 的间距分难度级别的,PAT(A)难度一般在 1.5-4.5 之间,保研考试一般在 2.0-5.0 之间.PAT(B)大概是 1.0-2.5 的难度.』. 个人认为,其中 1066 模拟 AVL 插入的实现有些细节容易弄错,而 1068 只要会简单的 DP,也就没有问题了,1065 和 10…
