建联通的树
```cpp
#include<bits/stdc++.h>
using namespace std;
const int n=6;//可以更改，下同
const int m=15;//
pair<int,int> e[100005];
map< pair<int,int>,bool > h;
int i;
int random(int x)
{
return rand()*rand()%x;
}
int main()
{
srand((unsigned)time(0));
freopen("data.in","w",stdout);
cout<<n<<' '<<m<<endl;
for (i=1;i<n;i++)
{
int fa=random(i)+1;
e[i]=make_pair(fa,i+1);
h[e[i]]=h[make_pair(i+1,fa)]=1;
}
for (i=n;i<=m;i++)
{
int x,y;
do
{
x=random(n)+1; y=random(n)+1;
} while(x==y||h[make_pair(x,y)]);
e[i]=make_pair(x,y);
h[e[i]]=h[make_pair(y,x)]=1;
}
random_shuffle(e+1,e+m+1);
for (i=1;i<=m;i++)
printf("%d %d %d\n",e[i].first,e[i].second,random(20000)+1);
cout<<m<<endl;
for (i=1;i<=m;i++)
{
int x,y;
x=random(n)+1;
do
{
y=random(n)+1;
} while(x==y);
printf("%d %d\n",x,y);
}
}
```
对拍程序
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
for (int T=1;T<=10000;T++)
{
system("data.exe");
double s=clock();
system("sol.exe");
double o=clock();
system("bf.exe");
if (system("fc bf.out sol.out"))
{
puts("Wa");
return 0;
} else printf("AC Round#%d time %.01f ms\n",T,o-s);
}
}
```
