# Palindrome Dates #
# Write a script to print all Palindrome Dates between 2000 and 2999. #
# The format of date is mmddyyyy. For example, the first one was on #
# October 2, 2001 as it is represented as 10022001. #

# [01][*][012][2][2][012][*][01]
# k j i i j k
#
# k - Months can only begin with 0 or 1.
# j - The second months digit needs all numbers e.g. January 01 to October 10 (and of course beyond).
# i - Days begin with 0,1,2,3, However all years begin with 2 so the corresponding number
# means all days end in 2. 32 is not a valid day so the 3 is not needed.
