#
# Task
#
# You are given a two lists A
# A and B
# Your task is to compute their cartesian product A
# A
# XB
# B
# .
#
# Example
# A = [1, 2]
# B = [3, 4]
#
# AxB = [(1, 3), (1, 4), (2, 3), (2, 4)]
#
#
# Note: A
# A
#  and B
# B are sorted lists, and the cartesian product's tuples should be output in sorted order.

# Input Format

# The first line contains the space separated elements of list A
# A
# .
#  The second line contains the space separated elements of list B
# B
# .
# Both lists have no duplicate integer elements.
# Constraints
# 0<A<30
# 0<A<30
# 0<B<30
# 0<B<30

# Output Format
# Output the space separated tuples of the cartesian product.
# Sample Input


#  1 2
#  3 4

# Sample Output
#  (1, 3) (1, 4) (2, 3) (2, 4)
