/* TASK #1
 * Square Secret Code
 *
 * The squate 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.
 *
 *
 * Executing program and output:
 *
 * $ echo 'the quick brown fox jumps over the lazy dog' | ./ch-1
 * tbjrd hruto eomhg qwpe unsl ifoa covz kxey
