My answers for the exercises:
Easy: Pull 4 numbers from the inbox, and push them out to the outbox in the reverse order.
00: 901
01: 320
02: 901
03: 321
04: 901
05: 322
06: 901
07: 902
08: 522
09: 902
10: 521
11: 902
12: 520
13: 902
14: 000
Medium: add a stack
The first number in the inbox tells you how many will follow, then add the rest up.
00: 901
01: 390
02: 590
03: 720
04: 901
05: 191

09: 390
10: 602
20: 591
21: 902
22: 000
30: 001
Hard: Divide
Divide the first number in the inbox by the second, end up with a quotient and some remainder. Push the quotient to the outbox, then push the remainder to the outbox.
