"""Find the Access Codes
In order to destroy Commander Lambda's LAMBCHOP doomsday device, you'll need
access to it. But the only door leading to the LAMBCHOP chamber is secured with
a unique lock system whose number of passcodes changes daily. Commander Lambda
gets a report every day that includes the locks' access codes, but only she
knows how to figure out which of several lists contains the access codes. You
need to find a way to determine which list contains the access codes once
