这题要特判m>c的时候

计算间隔时-1，计算结果时不要++ans，就没问题了
```cpp
#include <iostream>
#include <algorithm>
using namespace std;
bool cmp(int a,int b){
return a>b;
}
int cow[202],ge[202];
int main(){
int m,s,c;
cin >> m >> s >> c;
for(int i = 0;i < c;i++){
cin >> cow[i];
}
sort(cow,cow+c);
for(int i = 0;i < c - 1;i++){
ge[i] = cow[i + 1] - cow[i]-1; //这里-1
}
sort(ge,ge+c,cmp);
int ans = cow[c - 1] - (cow[0] - 1);
for(int i = 0;i < m - 1;i++){
ans-=ge[i]; //这里去掉++ans
}
cout << ans << endl;
return 0;
}
```
