• This week’s missions: Landing Site and Power Plants


Hi, there

Great news! We’ve significantly improved website’s speed performance. Enjoy!

Better handling DataTypes: Now your function can return any iterable as well as numpy types (including np.array)

Test yourself and have fun with the missions we have for you:

The first mission is called the “Landing Site” created by kurosawa4434 and here you need to find a set of all the candidate landing sites by being given a set of obstacle hexes on the Moon.

assert landing_site({'E5', 'E7', 'F4', 'F6', 'G4', 'G6', 'H3', 'H5'}) == {'C3', 'J7'}
assert landing_site({'A4', 'C2', 'C6', 'C9', 'D4', 'D7', 'F1', 'F5',
                    'F8', 'G4', 'H7', 'I2', 'I5', 'I9', 'K3', 'K8', 'L5'}) == {'B7', 'E3', 'J6'}

The second one is “Power Plants” created by kurosawa4434 where you have to place the given power plants in a proper way and supply power to all the cities.

power_plants({('A', 'B'), ('B', 'C'), ('C', 'D'), ('D', 'E')}, [2]) == {'C': 2}
power_plants({('A', 'B'), ('B', 'C'), ('C', 'D'), ('D', 'E'), ('E', 'F')}, [1, 1]) == {'B': 1, 'E': 1}
power_plants({('A', 'B'), ('B', 'C'), ('A', 'D'), ('B', 'E')}, [1, 0]) == {'B': 1, 'D': 0}
