#### 在输入后面排序一下（就改了一点）
__AC code:__
------------
```cpp
#include<cstdio>
#include<iostream>
#include<cmath>
#include<algorithm>
using namespace std;
int L,N;
int p[5005];
int mint,maxt;
int main()
{
scanf("%d",&L);
scanf("%d",&N);
for(int i = 1; i <= N; ++i)
cin >> p[i];
sort(p + 1, p + N + 1);
for(int i=1;i<=N;i++)
{
mint=max(min(p[i],L+1-p[i]),mint);
maxt=max(max(p[N],L+1-p[i]),maxt);
}
printf("%d %d",mint,maxt);
return 0;
}
```
