#
#        USAGE: ./14002.awk [ INFILE ]
#
#  DESCRIPTION: Print the Kth element of the sorted multiplication table
#               of I and J. Provide input of J, J and K on each line of
#               INFILE or STDIN.

# REQUIREMENTS: Requires asort which is a gawkism so standard awk will
#               likely not work.
