Number of Sides
You are given a list of coordinates of the vertices of the triangles (A list of tuples of 3 tuples of 2 integers) into which a polygon is divided. These share at least one side with the other triangle (which also shares two vertices). You have to return the number of sides of the original polygon as an integer.
Examples:
assert number_of_sides([((1, 1), (1, 3), (3, 3)), ((1, 1), (3, 1), (3, 3))]) == 4
assert number_of_sides([((1, 1), (2, 1), (2, 3)), ((2, 1), (2, 3), (3, 1))]) == 3
assert number_of_sides([((1, 1), (2, 3), (3, 1)), ((2, 3), (3, 1), (4, 3)),
((2, 3), (3, 5), (4, 3)), ((3, 1), (4, 3), (5, 1))]) == 3
NOTE:
- That polygon has no holes.
Input: The list of coordinates of the triangles (A list of tuples of 3 tuples of 2 integers) (int).
Output: The number of sides (An integer) (int).
Precondition:
- x >= 0, y >= 0
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.
