R2-D2 and C-3PO are friends. R2-D2 boards a spacecraft bound to a galaxy far, far away, but is always in contact with C-3PO, also, each one replies, as and when a message is received. R2-D2 started a conversation just after travelling a light-year. If there are total n messages in the conversation, what is the distance between the friends, just after R2-D2 said goodbye, in light-years?
FYI:
0 Relativity is eliminated
2 Messages travel at speed of light
4 Speed of spaceship is 1
times that of light
times that of light 6 X is more than 1; function must return 0, if otherwise...

The problem statement is useless. They weren't in constant contact, and the answers line up with when C-3PO sent goodbye, not R2-D2. Perhaps this will work:
R2-D2 and C-3PO are friends on Alderaan. R2-D2 boards a spacecraft at speed c/x bound to a galaxy far, far away while C-3PO remains on Alderaan. On reaching the marker 1 light year out from Alderaan, R2-D2 sends a message back to C-3PO. C-3PO and R2-D2 reply each reply as a message is received, until n messages are sent. When C-3PO sent their last message, how far away, in light years, was R2-D2 by 3PO's reckoning?
The problem description does seem correct to me. It just needs to fix the last question: "what is the distance between the friends, just after any of them said goodbye, in light-years? "C3PO could be the last to send a message when n is even.
SORRY! LOST IN TRANSLATION..
