# TASK #1
# Square Secret Code
#
# The square secret code mechanism first removes any space from the original
# message. Then it lays down the message in a row of 8 columns. The coded
# message is then obtained by reading down the columns going left to right.
#
# For example, the message is "The quick brown fox jumps over the lazy dog".
#
# Then the message would be laid out as below:
#
# thequick
# brownfox
# jumpsove
# rthelazy
# dog
#
# The code message would be as below:
#
# tbjrd hruto eomhg qwpe unsl ifoa covz kxey
#
# Write a script that accepts a message from command line and prints the
# equivalent coded message.
