344. Reverse String（python+cpp）

题目：

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

Example 1:

Input: “hello”
Output: “olleh”
Example 2:
Input: “A man, a plan, a canal: Panama”
Output: “amanaP :lanac a ,nalp a ,nam A”

解释：
字符串翻转。

python代码：

class Solution(object):
    def reverseString(self, s):
        """
        :type s: str
        :rtype: str
        """
        return s[::-1]

c++代码：

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