344. Reverse String

{leetcode}/problems/reverse-string/[LeetCode - Reverse String^]

这个跟 {leetcode}/problems/valid-palindrome/[Valid Palindrome - LeetCode^] 的思路类似,都是"左右夹击"。

Write a function that reverses a string. The input string is given as an array of characters char[].

Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory.

You may assume all the characters consist of printable ascii characters.

Example 1:

Input: ["h","e","l","l","o"]
Output: ["o","l","l","e","h"]

Example 2:

Input: ["H","a","n","n","a","h"]
Output: ["h","a","n","n","a","H"]
