You need to add some trees and keep them evenly spaced.
You are given a list of integers as an input value. This is the position of an existing tree. You must return the minimum number of additional trees needed so that they could be evenly spaced.
- Positions of the existing trees are already sorted.
- All positions of trees are integers.
evenly_spaced_trees([0, 2, 6]) == 1 # add to 4. evenly_spaced_trees([1, 3, 6]) == 3 # add to 2, 4 and 5. evenly_spaced_trees([0, 2, 4]) == 0 # no need to add.
Input: The position of the existing trees (a list of integers).
Output: The minimum number of additional trees (an integer).
How it is used:
- 0 ≤ Position of tree ≤ 100
- 3 ≤ The existing trees
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
(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 --ff
checkio install-plugin --chromium
