#344. 　Reverse String      

Write a function that takes a string as input and returns the string reversed.

Example:
Given s = "hello", return "olleh".

题解：回文串，没什么好说的好像。

class Solution {
public:
    string reverseString(string s) {
        char temp;
        int from=0;
        int to=s.size()-1;
        while(from<to)
        {
            temp=s[from];
            s[from++]=s[to];
            s[to--]=temp;
        }
        return s;
    }
};
