题目描述:
就是有n种硬币,每种硬币有两个属性(价值,数目)。问用给定的硬币组成K面值,有多少种方案?
解题思路:
赤果果的多重背包,简单搞一下就好了。席八!烦烦烦。今天绝对是出门刷提前没看黄历,刚开始套了一个多重背包板子,蓝而跑出来的答案并不对,改来改去就错在细节的地方。
#include <cmath>
#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>
using namespace std; typedef long long LL;
const int mod = ;
const int maxn = ;
int dp[][maxn], a[], c[]; int main ()
{
int T;
scanf ("%d", &T);
for (int t=; t<=T; t++)
{
int n, k;
scanf ("%d %d", &n, &k);
memset (dp, , sizeof(dp));
dp[][] = ; for (int i=; i<=n; i++)
scanf ("%d", &a[i]);
for (int i=; i<=n; i++)
scanf ("%d", &c[i]); for (int i=; i<=n; i++)
for (int j=; j<=c[i]; j++)
for (int x=k; x>=a[i]*j; x--)
{
dp[i][x] = (dp[i][x] + dp[i-][x-a[i]*j]) % mod;
} printf ("Case %d: %d\n", t, dp[n][k]);
}
return ;
}
