On the same path
You have to write a function that receives a tree – potentially large but finite –
and a list of pairs of tree's nodes.
For each pair, you must determine if the two nodes are on a same path (True) in the tree or not (False),
then return an iterable/list of these booleans.
Input: two arguments:
- a tree as a tuple (a node, list of sub-trees)
- a list of pairs (the tuples of two nodes)
Output: An iterable/list of booleans.
on_same_path(
('Me', [('Daddy', [('Grandpa', []),
('Grandma', [])]),
('Mom', [('Granny', []),
('?', [])])]),
[('Grandpa', 'Me'), ('Daddy', 'Granny')],
) == [True, False]
on_same_path(
(1, [(2, [(4, []),
(5, [(7, []),
(8, []),
(9, [])])]),
(3, [(6, [])])]),
[(1, 5), (2, 9), (2, 6)],
) == [True, True, False]
on_same_path(
(0, [(1, [(2, []),
(3, [])]),
(4, [(5, []),
(6, [])]),
(7, [(8, []),
(9, [])])]),
[(4, 2), (0, 5), (2, 3), (9, 2), (6, 4), (7, 8), (8, 1)],
) == [False, True, False, False, True, True, False]
Preconditions:
- the tree is finite and has less than 1000 nodes
- for each given tree all nodes are either the integers or strings
- len(pairs) ≤ 32

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.
