Connect Stars Connect Stars

In this mission you'll have to make the Minimum spanning tree (Wikipedia) .

You are given a list of coordinates of vertices. Each coordinate is a tuple of x (integer) and y (integer).
You have to return a list (or an iterable) of lines that connect all vertices. The total length of lines should be the minimum. Each line is a tuple of two integers. These integers represent the index of list of input.

NOTE:

  • The output of tests has a unique combination of lines.

Example:

connect_stars([(1, 1), (4, 4)])) == [(0, 1)]                         # or [(1, 0)]
connect_stars([(1, 1), (4, 1), (4, 4)])) == [(0, 1), (1, 2)]         # or [(1, 2), (0, 1)] , [(1, 0), (2,1)] etc
connect_stars([(6, 6), (6, 8), (8, 4), (3, 2)])) == [(0, 1), (0, 2), (0, 3)]   # or [(2, 0), (0, 3), (1, 0)] etc

example

Input:

  • A list of coordinates of vertices.
    • Each coordinate is a tuple of x (integer) and y (integer).

Output:

  • A list (or an iterable) of lines.
    • Each line is a tuple of two integers. These integers represent the index of list of input.
    • The order of lines and each index is arbitrary (see examples).

Precondition:

  • 2 ≤ len(input) ≤ 50
  • 0 ≤ x (,y) ≤ 999

CheckiO Extensions

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.
