Reverse a String I - DSA Practice

Given an input string as an array of characters, write a function that reverses the string.

Input : s = ["h", "e", "l", "l", "o"]

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

Explanation : The given string is s = "hello" and after reversing it becomes s = "olleh".

Input : s = ["b", "y", "e" ]

Output : ["e", "y", "b"]

Explanation : The given string is s = "bye" and after reversing it becomes s = "eyb".

Pick the correct output for the given input

Input : s = ["h", "a", "n", "n", "a", "h"]

['h', 'a', 'n', 'n', 'a', 'h']['h', 'n', 'a', 'n', 'a', 'h']['h', 'n', 'a', 'a', 'n', 'h']['h', 'a', 'n', 'a', 'n', 'h']

Still unsure what the problem is asking ?
