Flood Area
Your task is to simulate a flood damage.
You are given a cross-section diagram (a string). It represents slopes and flatlands by '/', '\' and '_' respectively. For example, the region of the following picture is shown by a raw string r"/\\///\_/\/\\\\/_/\\///__\\\_\\/_\/_/". Notice, that single backslash "\" escapes following character. So to get backslash just as a character without special functionality, you need to escape every needed backslash string with another one or use raw string.
Assume that the rain is falling endlessly and the water overflowing from the region is falling into the sea from both sides. In the following example the rain will create floods in 4, 2, 1, 19 and 9 areas respectively.
You should return a list or other Iterable (tuple, iterator, generator) of the numbers of floods from the left side of the cross-section diagram. If there aren’t any floods, return [] (or an empty Iterable).
Examples:
assert list(flood_area("\\\\//")) == [4]
assert list(flood_area("_/\\//")) == [1]
assert list(flood_area("\\\\/_")) == [1]
assert list(flood_area("\\\\_\\\\_/_/\\//_")) == [18]
Input: A cross-section diagram (a string).
Output: The numbers of floods as list or other Iterable (tuple, iterator, generator) of integers.
Precondition:1 ≤ len(diagram) ≤ 500

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.
