1. Take input from the user, repeat it to them.
2. Take input from the user, tell them the length of the input.
3. Take input from the user, tell them if the input is a palindrome.
4. Take input from the user, repeat it to them backwards.
5. Take input from the user, spit out all of the letters (but no punctuation) in order.
6. Tell the user all the files in the current directory.
I got through 1, 2 and 4 alright, but I am having trouble with 3. I am thinking I would have to take what they input, spell it backwards, then compare it with the word the user in-putted to see if they are equal?
