Hexagonal Islands
This is the mission similar to the “Calculate Islands” mission where you’re dealing with a hexagonal grid. Please, help the robots again.
The size of the hexagonal grid is 12x9 ('A1' to 'L9').
- It’s characteristics:
- the alphabet letters represent columns and numbers represent rows;
- it’s flat topped;
- the even columns are being shoved down.
You are given a set of coastal hexes for all islands as input value. You have to find all islands that those hexes represent and return a list (tuple or iterable) of that size.
Note:
- The islands don't include other islands.
- If there is no island (input == set ()), return [].
- There are also case that no sea. (In this case your answer is [108].)
Examples:
sorted(hexagonal_islands({'C5','E5','F4','F5','H4','H5','I4','I6','J4','J5'})) == [1, 3, 7]
sorted(hexagonal_islands({'A1','A2','A3','A4','B1','B4','C2','C5','D2', 'D3','D4','D5',
'H6','H7','H8','I6','I9','J5','J9','K6','K9','L6','L7','L8'}) == [16, 19]
sorted(hexagonal_islands(set())) == []
Input: The coastal hexes of all islands (a set of strings).
Output: The sizes of all islands (an iterable ( a list or tuple) of integers).
How it is used:
For recognizing the area on the hexagonal grid.Preconditions:
- all(re.fullmatch('[A-L][1-9]', i) for i in input)

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=py config --key=
Sync solutions into your local folder
checkio sync
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium
Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
