Create Intervals (iterator version)
From a set of ints (which will be an iterator of the sorted list) you have to create a list of closed intervals as tuples, so the intervals are covering all the values found in the set. After that you have to create an iterator object which is linked to this list.
A closed interval includes its endpoints! The interval 1..5 , for example, includes each value x that satisfies the condition 1 <= x <= 5 .
Values can only be in the same interval if the difference between a value and the next
smaller value in the set equals one, otherwise a new interval begins. Of course, the
start value of an interval is excluded from this rule.
A single value, that doesn’t fit into an existing interval becomes the start- and
endpoint of a new interval.
Input: An iterator of the sorted list of ints.
Output: An iterator object linked to the list of tuples.
Examples:
list(create_intervals(iter(sorted(list({1, 2, 3, 4, 5, 7, 8, 12}))))) == [
(1, 5), (7, 8), (12, 12)]
list(create_intervals(iter(sorted(list({1, 2, 3, 6, 7, 8, 4, 5}))))) == [
(1, 8)]
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.
