```cpp
#include<bits/stdc++.h>
using namespace std;
int n,m,a[5005],minn,maxx;
int main()
{
cin>>n>>m;
for (int i=1;i<=m;i++)
{
cin>>a[i];
}
sort(a+1,a+1+m);
for (int i=1;i<=m;i++)
{
minn=max(minn,min(a[i],n+1-a[i]));
maxx=max(n+1-a[1],a[m]);
}
cout<<minn<<" "<<maxx;
return 0;

不用那么复杂吧？
```cpp
#include <bits/stdc++.h>
using namespace std;
const int N=5e3+10;
int a[N];
int l,n,mint,maxt;
int main(){
scanf("%d",&l);
scanf("%d",&n);
for(int i=1;i<=n;i++){
scanf("%d",&a[i]);
mint=max(mint,min(a[i],l-a[i]+1));
maxt=max(maxt,max(a[i],l-a[i]+1));
}
printf("%d %d",mint,maxt);
return 0;
}
```

我一开始min=-1，#1也WA，后来发#1输入的n=0，要输出0 0...
