I'd like to embark on a walking tour of Sydney's light rail stations.
I want to visit 10 stations then return back to the place I started.
I won't actually be catching any services! I just want to admire each station's amenities.

However, there's a certain set of rules I must follow:

1. I will be starting and ending at the corner of Thomas St & Jones St; https://goo.gl/maps/jgar0
2. A station can be visited any number of times, or never!
3. After visiting an odd station (the 1st, 3rd, 5th, 7th, 9th), I can visit any station next. (even)
4. After visiting an even station (the 2nd, 4th, 6th, 8th), the next (odd) station must be at least THREE stops away.

May your signals all trap 
May your references be bounded 
All memory aligned 
Floats to ints rounded 

Remember ...

Non-zero is true 
++ adds one 
Arrays start with zero
