I totally read that as "Entry fee is optional"

The problem statement might be flawed by trying to frame it in an
electrical context.  The author uses the phrase "Electricity always
follows the path of least resistance" but I understood that current
could flow down multiple routes in proportion inverse to the
resistances, i.e. that if one path had a 10% higher resistance, it
would receive 10% less current, not that all current would flow
through the less resistive(?) path.

Feel free to correct my knowledge of physics and electrical engineering though.

I think the problem is just looking for a simple shortest path
algorithm  Dijkstra or something.
