# Problem 3

# A 'for' loop takes every element in a variable (string,etc)
# and works with each one to do some operation.
# This 'for' loop will look at every letter in the input and will
# increment the 'vowelcount' variable by 1.

# Using the string reversal trick learned for problem 2, we compare the
# input variable with it's reversed form. It will print that the word
# is or is not a palindrome.
