@[Him2009](/user/322792) 可以的, 测试了10个0,代码:
```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
freopen("file.txt","w",stdout);
for(int i = 0;i < 62500000;i += 2){
cout << 0;
cout << 0;
}
return 0;
}
```

~~当然你嫌这个不够快还可以再展开一下~~

@[Him2009](/user/322792) ~~类似快速幂的思路，虽然是手写，先写一个 0，然后复制粘贴变成两个，复制粘贴变成四个~~
直接输出呗你还想怎么样

@[AMIRIOX無暝](/user/320697) 你这个跟普通的没区别吧，都是执行 `cout<<0;` 总共执行了 6250000 遍

@[rui_er](/user/122461) 常数优化, CPU有关

@[HairlessVillager](/user/315991) 复杂度不变, 常数优化了 和快读一样都是~~今年省选~~卡常
