这两个数据结果是 5600吧
故意用了一下 spfa 但是不知怎么  就是不过 管理员能不能 给点数据 mabodx@gmail.com
#include<iostream>
#include<cmath>
using namespace std;
 
 
#define e 1000

int map[e][e];
int flag[e];

struct node{
	int r;
	int l;
	int s[e*100];
}q;

int d[e];
int use[e];

void spfa(int m)
{
	int i,n ;
	memset(d,0,sizeof(d));
	memset(use,0,sizeof(use));
	for(i=0; i<=m; i++)
	{
		d[i]=INT_MAX;
	}
	d[0]=0;
	memset(q.s,0,sizeof(q.s));
	q.r=q.l=-1;
	q.s[++q.l]=0;
	use[0]=1;
	while(q.r<q.l)
	{
	 
		int temp=q.s[++q.r];
		use[temp]=0;
		for(i=0;i <=m ;i++)
		{
			if(i!=temp)
			{
				if(  map[temp][i]!=INT_MAX && d[temp]!=INT_MAX )
					if( flag[i]==0 && d[i] > d[temp]+map[temp][i]  )
					{
						 d[i]=d[temp]+map[temp][i];
					 
						if(use[i]==0)
						{	q.s[++q.l]=i;
							use[i]=1;
						}
					}
				 
			}

		}
	}
}

int main()
{

	printf("%d\n", d[1]);
}
