Given an int, determine if its base-10 representation (as a String) is a palindrome. A palindrome reads the same forwards and backward. The sign (-) is part of the representation and should be considered.

HINT: checking for a palindrome involves a loop, usually. If you haven't learned loops yet you can skip this problem. Or, there is a class called StringBuilder (not on the exam, but quite useful sometimes and part of java.lang) which has a constructor accepting a String, a handy reverse method and a toString that outputs its contents.
