+# 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.
