/* ============ Task ============

Complete the reverseString function; it has one parameter, s. You must perform the following actions:

1. Try to reverse string s using the split, reverse, and join methods.
2. If an exception is thrown, catch it and print the contents of the exception's message on a new line.
3. Print s on a new line. If no exception was thrown, then this should be the reversed string; if an exception was thrown, this should be the original string.
