输出的东西令我难以理解、一言难尽……

刚刚自己改了以后更离谱了
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
string a;
bool first=false;
cin>>a;
int l=a.length();
for(int i=l-1;i>-1;i++)
{
if(a[i]==0)
{
if(first==true)
{
cout<<a[i];
}
}
else if(a[i]!='-')
{
first=true;
cout<<(int)(a[i]-48);
}
}
return 0;
}
```

这不行了吗
思路清晰，代码简洁，~~极致压行。~~
```
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n=0,s=0;
cin>>n;
while(n){ s=s*10+n%10; n/=10;}
cout<<s;
return 0;
}
```

```
#include<bits/stdc++.h>
using namespace std;int main(){int n=0,s=0;cin>>n;while(n){ s=s*10+n%10; n/=10;}cout<<s;return 0;}
```
2行的代码，拿去抄吧
