# 3.2 A palindrome is a number or a text phrase that reads the same backwards or forwards.
# For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611.
# Write a program that reads in a five-digit integer and determines whether it is a palindrome.
# (Hint: Use the division and modulus operators to separate the number into its individual digits.)
