The Codeless Code: Case 81 Bubble Sort 
======

 Walking the halls of his abbey late at night, master Bawan
came upon a monk in distress. A morning deadline was fast
approaching, and after three all-nighters the exhausted monk
had dropped his only remaining coins into the soda machine
without first noticing the paper sign taped to it. The sign
read OUT OF ORDER in large red capitals.

“Can you fix it?” asked the monk, who knew of Bawan’s skill
with primitive machines.

Bawan studied the machine for a moment, then crossed out the
letters of the sign and under them wrote DEFOOORRTU.
Immediately a soda can dropped into the chute.

Satisfied, Bawan continued on his way.
