[Solved] Quickest Algorithm to write for this?

I would start small, and build up. The smallest (n=1) is simply: * that clearly doesn’t work since there are 0 neighbors (and even number). So no solution exists for n=1. Next, try n=2. Only one choice: ** This works. Now what about n=3? Doesn’t work, no solution for n=3. Now, how can you add … Read more
