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"] | |||
