题目简述：

大体意思就是输入一串字符，然后反向输出

解题思路：

使用String变量解决（char也可以），但是要注意回车键的储存，不然会出现两个空行

题目细节：

就是思路里所说的回车键问题

代码：

#include<bits/stdc++.h>
using namespace std;
int main()
{
int n,sum;
char c;
string str;
cin>>n;
cin.get(c);
for(int i=0;i<n;i++)
{
getline(cin,str);
sum=str.size();
for(int t=sum-1;t>=0;t--)
{
cout<<str[t];
}
cout<<endl;
}
}

体会：

一开始发现回车键这个问题时相当难受，不知道怎么解决，还是上网查了一下才知道回车键要用char来储存，知道的还是太少了
