样例都没过，自己看

@[smxcys666](/user/969221) 可以简化
```cpp
#include<bits/stdc++.h>
using namespace std;
short a,b,c[400],d;
int main(){
cin>>a>>b;
for(short i=a;i<=b;i++){
if(i%4==0&&(i%100!=0||i%400==0)){
c[d]=i;d++;
}
}
cout<<d<<endl;
for(short i=0;i<d;i++) cout<<c[i]<<' ';
return 0;
}
```

@[smxcys666](/user/969221) ~~可能有些抽象，~~
$d$ 是数组长度，当时我还不会```vector```

@[_buzhidao_](/user/917775) Sorry，I am not understand when there is a "数组" here~~~

@[smxcys666](/user/969221) 网速刚刚好慢啊，是不是又有人卡评测了

@[_buzhidao_](/user/917775) d没有初始值。
