+
+### ❓ Description
+
+<br/>
+
+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 `s` 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**](https://baike.baidu.com/item/%E5%8E%9F%E5%9C%B0%E7%AE%97%E6%B3%95) **修改输入数组**、使用 `O(1)` 的额外空间解决这一问题。
+
+<br/>
+
+**示例 1：**
+
+```
+输入: s = ["h", "e", "l", "l", "o"]
+输出: ["o", "l", "l", "e", "h"]
+```
+
+**示例 2：**
+
+```
+输入: s = ["H", "a", "n", "n", "a", "h"]
+输出: ["h", "a", "n", "n", "a", "H"]
+```
+
+<br/>
+
+**提示：**
+
+* `1 <= s.length <= 10^5`
+* `s[i]` 都是 `ASCII` 码表中的可打印字符
+
+---
+
+### ❗ Solution
+
+<br/>
+
+#### Java
+
+```
+class Solution {
+    public void reverseString(char[] s) {
+        for (int left = 0, right = s.length - 1; left < right; left++, right--) {
+            char temp = s[left];
+            s[left] = s[right];
+            s[right] = temp;
+        }
+    }
+}
+```
