你这不可做吧……C语言空main不导入头文件都有1324kb内存

实测不可过 (原 $\text{AC}$ 的所有程序)。发一个较优的代码：
```cpp
#include<cstdio>
#include<cmath>
#include<cctype>
using namespace std;
inline void read(int&x){
char c=getchar();x=0;
while(!isdigit(c))c=getchar();
while(isdigit(c))x=(x<<1)+(x<<3)+c-48,c=getchar();
}
int main(){int x;
read(x);
int sqt = sqrt(x+.5);
if(sqt*sqt==x)putchar('Y');
else putchar('N');
}
```

这个代码86分...
```cpp
#include<stdio.h>
int main()
{
unsigned int x=0,i;
while(i=getchar(),'0'<=i&i<='9') x=x*10+i-'0';
for(i=0;i*i<=x;i++)
if(i*i==x)
{
putchar('Y');
return 0;
}
putchar('N');
}
```

@[xenonex](/space/show?uid=86061) 这题可能只能用汇编做了.....

#include<iostream>
using namespace std;
int main(){
return 0;
}
这东西mle
