#include<bits/stdc++.h>
using namespace std;
int main()
{
    string s;
    bool y=false;
    cin>>s;
    int n;
    n=s.size();
    if(s[0]=='-') cout<<"-";
    for(int i=n-1;i>=0;i--)
    {
        if(s[i]!='-'&&s[i]!='0') cout<<s[i]-48;
    }
}

@zengxiangtuo 为什么要减48？

by ChthollyMeow @ 2020-05-17 18:40:47

@zengxiangtuo 第二，会多输出一个负号

@_珂朵莉 减和不减不是一样的吗?

我不是有判断吗

by imbecile @ 2020-05-17 18:53:31

样例也没错呀

by SIXIANG32 @ 2020-05-17 18:53:59

@zengxiangtuo 不对，是中间的0
