# Story
# Your online store likes to give out coupons for special occasions.
# Some customers try to cheat the system by entering invalid codes or using expired coupons.

# Task
# Your mission:
# Write a function called checkCoupon which verifies that a coupon code is valid and not expired.

# A coupon is no more valid on the day AFTER the expiration date.
# All dates will be passed as strings in this format: "MONTH DATE, YEAR".

# Examples:
# checkCoupon("123", "123", "July 9, 2015", "July 9, 2015")  == True
# checkCoupon("123", "123", "July 9, 2015", "July 2, 2015")  == False
