// Create a function that reverses a string:
// 'Test this'
// 'siht tset'

// Input: String
// Output: String with characters in reverse
// Plan: Take the input string, separate each characters and insert into an array,
// create an empty array variable, loop through the input array backwards,
// insert those characters into the empty array variable
// Time complexity: O(n)
