344. 反转字符串 #90

Open reed-qu opened 4 years ago

reed-qu commented 4 years ago

原始问题:344. 反转字符串

编写一个函数,其作用是将输入的字符串反转过来。输入字符串以字符数组 char[] 的形式给出。

不要给另外的数组分配额外的空间,你必须原地修改输入数组、使用 O(1) 的额外空间解决这一问题。

你可以假设数组中的所有字符都是 ASCII 码表中的可打印字符。

示例 1:

输入:["h","e","l","l","o"]
输出:["o","l","l","e","h"]

示例 2:

输入:["H","a","n","n","a","h"]
输出:["h","a","n","n","a","H"]

解题示例


class Solution:
    def reverseString(self, s: List[str]) -> None:
        """
        Do not return anything, modify s in-place instead.
        """
        pass
