Leetcode题目：Reverse String
题目：
Write a function that takes a string as input and returns the string reversed.
Example:
Given s = "hello", return "olleh".
解答：这个题目超级无敌简单，就是把一个string给逆过来输出。
代码：
class Solution {
public:
string reverseString(string s) {
stringstream res;
res.clear();
for(int i = s.length() - 1;i >= 0;i--)
{
res << s[i];
}
return res.str();
}
};
