Create Intervals (generator version) Create Intervals (generator version)
Undefined
English RU

From a set of ints you have to create a list of closed intervals as tuples, so the intervals are covering all the values found in the set.
In this mission you should use the 'yield' to make your function a generator.

A closed interval includes its endpoints! The interval 1..5 , for example, includes each value x that satifies 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 does not fit into an existing interval becomes the start- and endpoint of a new interval.

Input: A set of ints.

Output: A list of tuples of two ints, indicating the endpoints of the interval. The list should be sorted by start point of each interval.

Examples:

create_intervals({1, 2, 3, 4, 5, 7, 8, 12}) == [(1, 5), (7, 8), (12, 12)]
create_intervals({1, 2, 3, 6, 7, 8, 4, 5}) == [(1, 8)]

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.
