Ivan is a postal worker who can travel at the speed of light. He's happy to relay thousands of messages per second between you and a friend. However, he can only transport one message at a time, and it has to fit on an index card.
Unfortunately Ivan is incredibly inattentive, so there are a few minor limitations in his service:
- Integrity: He cannot guarantee that all messages will arrive in their entirety
- Order: He cannot guarantee delivered messages will arrive in the same order that they were sent
- Recipient: He cannot guarantee that messages will always be delivered to the correct recipient
###Instructions
