滑動窗口-leetcode344-反轉字符出啊

編寫一個函數，其作用是將輸入的字符串反轉過來。輸入字符串以字符數組 s 的形式給出。

不要給另外的數組分配額外的空間，你必須原地修改輸入數組、使用 O(1) 的額外空間解決這一問題。

示例 1：

輸入：s = ["h","e","l","l","o"]
輸出：["o","l","l","e","h"]
示例 2：

輸入：s = ["H","a","n","n","a","h"]
輸出：["h","a","n","n","a","H"]
提示：

1 <= s.length <= 105
s[i] 都是 ASCII 碼錶中的可打印字符

class Solution {
    public void reverseString(char[] s) {
        int left = 0;
        int right = s.length-1;
        while(left < right){
            char temp = s[left];
            s[left] = s[right];
            s[right] = temp;
            left++;
            right--;
        }

    }
