    344 - Reverse String.

    Easy

    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”]
