【LeetCode】344. Reverse String

Difficulty: Easy

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

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

简单地翻转字符串，因为太懒，不想写个for循环，直接调用reverse函数，时间复杂度O(n).

class Solution {
public:
    string reverseString(string s) {
    string res = s;
    reverse(res.begin(),res.end());
    return res;
	  
}
};
