Ghost leg is a well-known method used to get random results. This mechanism has the effect of changing the order in the list.

Examples:

assert follow_ghost_legs(3, [(1, 2), (2, 3), (1, 2)]) == [3, 2, 1]
assert follow_ghost_legs(4, [(2, 3), (1, 2), (2, 3), (3, 4)]) == [3, 2, 4, 1]
assert follow_ghost_legs(5, [(3, 4), (4, 5), (3, 4), (2, 3), (3, 4)]) == [1, 5, 4, 2, 3]
assert follow_ghost_legs(6, [(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)]) == [ 2, 3, 4, 5, 6, 1]

You are given the number of vertical lines and a list of legs as input values.

  • If the number of vertical lines is 3, then the starting points are 1, 2, and 3 respectively.
  • The leg is a tuple of two integers, which represent the two vertical lines connected by the leg. (The leg always connects adjacent vertical line).
  • The order of legs represents the level at which they are placed (first leg is the top, and last leg is the bottom).

Follow the ghost legs and return a list of converted numbers.

Input: The number of vertical lines and a list of legs (an integer and a list of tuple of two integers).

Output: A list of converted numbers (a list of integers).

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.
