两种方法解决这个问题。。 背包方法;; #include<stdio.h> #include<string.h> int a[166000]; int dp[166600][3]; int max(int a,int b) { a=a>b?a:b; return a; } int main() { int m,n,i,k; while(scanf("%d",&m)!=EOF) {
传送门 题目描述 给定 n n n个数,每个数 a i a_{i} ai都有一个对应的 c o s t i cost_{i} costi,现在你需要从中取若干种数,每种数可以有若干个,将他们相加减可以得到任意一个整数,问你最小的花费是多少 分析 首先我们可以把问题转换成选若干个数凑出一个1,因为凑出来1,就可以凑出来任意个数 根据裴蜀定理我们知道,方程 a x + b y = g c
Problem - D - Codeforces 题目意思是:有k个区间,每一个的左边为l,右边为r。刚开始你的点在0,每一次操作可以把点移动至多k个单位,但要让你的点的pos一直在[l,r]。要求求出最小的k。 二分答案其实我也一直不是很会,emmm。 如果k的值比答案大的话,那么肯定是可以的,所以直接二分就行。 #include<bits/stdc++.h>using namespa

思路 二分 k k k 。对于当前 [ l , r ] [l,r] [l,r] 移动 k k k 之后能到达的最大范围 [ l − k , r + k ] [l-k,r+k] [l−k,r+k] ,如果下一段线段与该范围无重合区间则该 k k k 过小,如果有重合区间则更新 [ l , r ] [l,r] [l,r] 为 [ m a x ( l − k , n e x t l ,
