Posted by cangratul at 2009-04-08 12:29:39 on Problem 1010 and last updated at 2009-04-08 12:38:30
客户要求的邮票总值范围是<=62的,每张邮票的面值<=3,本人二分测的,测试程序如下,如有任何疑问,请保留···

#include<cstdio>
#include<algorithm>
#include<string>
#include<iostream>
#include<cmath>
#include<vector>
#include<fstream>
#include<map>
#include<queue>
using namespace std;
int ans[63][8],p[25],a[4],n;
char h[4];
void orz(int sum,int index,int pre,int cnt,int dcnt)
{
	if(index>=n) return;
	orz(sum,index+1,pre,cnt,dcnt);
	if(index!=pre) {dcnt++; pre=index;}
	a[cnt]=p[index];
	cnt++;
	sum+=p[index];
	if(dcnt==ans[sum][0]&&cnt==ans[sum][1]&&p[index]==ans[sum][2]) ans[sum][3]=1;
	else if(dcnt>ans[sum][0]||dcnt==ans[sum][0]&&cnt<ans[sum][1]||dcnt==ans[sum][0]&&cnt==ans[sum][1]&&p[index]>ans[sum][2])
	{
		ans[sum][0]=dcnt; ans[sum][1]=cnt; ans[sum][2]=p[index]; ans[sum][3]=0;
		for(int i=4;i<4+cnt;i++) ans[sum][i]=a[i-4];
	}
	if(cnt!=4) orz(sum,index,pre,cnt,dcnt);
}
int main()
{
	int tmp;
	while(scanf("%d",&tmp)!=EOF)
	{
		n=0;
		memset(h,0,sizeof(h));
		for(int i=0;i<63;i++) ans[i][0]=-1;
		do
		{
			if(tmp==0) break;
			if(h[tmp]<5) {p[n++]=tmp; h[tmp]++;}
		}while(scanf("%d",&tmp)!=EOF);
		sort(p,p+n);
		orz(0,0,-1,0,0);
		while(scanf("%d",&tmp)&&tmp)
		{
			if(ans[tmp][0]==-1) printf("%d ---- none\n",tmp);
			else if(ans[tmp][3]) printf("%d (%d): tie\n",tmp,ans[tmp][0]);
			else 
			{
				printf("%d (%d):",tmp,ans[tmp][0]);
				for(int i=0;i<ans[tmp][1];i++) printf(" %d",ans[tmp][4+i]);
				putchar('\n');
			}
		}
	}
};
