🧑🚀문제링크: https://leetcode.com/explore/interview/card/top-interview-questions-easy/127/strings/879/
Write a function that reverses a string. The input string is given as an array of characters s.
You must do this by modifying the input array in-place with O(1) extra memory.
Example 1:
Input: s = ["h","e","l","l","o"]
Output: ["o","l","l","e","h"]
Example 2:
Input: s = ["H","a","n","n","a","h"]
Output: ["h","a","n","n","a","H"]
Constraints:
* 1 <= s.length <= 105
* s[i] is a printable ascii character.
