# == Question:
# 12 people stand in two rows, 6 per row. People in each row must be
# arranged by their height and person in the second row must be taller 
# than the one up front. Well, how many kinds of arrangement can be?
#
# == Solution:
# Suppose that person1 to person12 are marked by their height ascent
# We find the following rules:
# 1. Person at the first position of row 1 must be person1
# 2. Person at the second positon of row 1 must be in person2...person3, and person
