On stage 7 Zero Extermination you are tasked to put all non-zero values from the inbox into the outbox. This one doesn't really have a simple "copy and paste my code" solution but it is still easy to get. What you need to do is look at your own specific inputs and construct a program that follows my instructions.

8 - Inbox Outbox
0 - Inbox
9 - Inbox Outbox
F - Inbox Outbox
0 - Inbox
0 - Inbox
-1 - Inbox Outbox
