```
#include<iostream>
using namespace std;
int main(){
const int maxn=1e9+5;
char a[maxn];
int i=1;
while(cin>>a[i])i++;
i--;
int d=i;
if(a[1]=='-'){
cout<<'-';
while(i>1){
if(a[i]=='0'&&i==d){i--;d--;continue;}
if(a[d]=='0'){d--;continue;}
cout<<a[i];
i--;
}
}
else{
while(i>0){
if(a[i]=='0'&&i==d){i--;continue;}
if(a[d]=='0'){d--;continue;}
cout<<a[i];
i--;
}
}
return 0;
}
```

其实可以用sprintf()函数来将整数化成字符串，再倒着输出，那样更简单!不用写太多行！！！
