怎么过不了,老是wrong 想看看牛人怎么写的#include <stdio.h>
#define MAXN 101
int n,q,xx[MAXN][MAXN];
void conn(int a,int b)
{
int i,j,i0,j0,temp;
if (a<b)
{temp=a;a=b;b=temp;}
for(i=1;i<=n;i++)
{
xx[b][i]=((xx[a][i]<xx[b][i])?xx[a][i]:xx[b][i]);
xx[i][b]=((xx[i][a]<xx[i][b])?xx[i][a]:xx[i][b]);
}
for(i=a;i<=n-1;i++)
for(j=1;j<=n;j++)
xx[i][j]=xx[i+1][j];
for(i=1;i<=n-1;i++)
for(j=a;j<=n-1;j++)
xx[i][j]=xx[i][j+1];
n--;
}
void input()
{
int i,j,a,b;
scanf("%d",&n);
for(i=1;i<=n;i++)
{
for(j=1;j<=n;j++)
scanf("%d",&xx[i][j]);
}
scanf("%d",&q);
for(i=1;i<=q;i++)
{
scanf("%d%d",&a,&b);
conn(a,b);
}
}
int solve()
{
int i,j,ci,cj,y,min;
y=0;
while(n!=1)
{
min=10000;
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)
if(xx[i][j]<min&&i!=j)
{
min=xx[i][j];
ci=i;cj=j;
}
y+=xx[ci][cj];
conn(ci,cj);
}
return y;
}
main()
{
input();
printf("%d\n",solve());
}
