The Dryad-Gate of Ilvenwood
Deep in Ilvenwood stands a ring of ancient oaks whose roots knot together into a living gate. The dryads who tend it have pinned their terms to the Bitwick board. The Rangers' Lodge needs a quick reckoning, made before each expedition sets out, of whether a party will be let through.
The dryads open the gate to a party only when all three of these hold:
1. The party has between 1 and 6 members, inclusive. 2. The party carries no iron. 3. The party arrives at night, or carries a dryad-seal, or both.
Write mayPass(size, iron, night, seal):
sizeis an integer (zero or more): the number of members in the party.ironis a boolean:trueif the party carries any iron.nightis a boolean:trueif the party arrives at night.sealis a boolean:trueif the party carries a dryad-seal.
Return true if the gate opens for the party under the three rules above. Otherwise return false.
