Flood Area Flood Area
Simple
RU English

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 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 an iterable) 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).

Example:

list(flood_area(r'\\//')) == [4]
list(flood_area(r'/\\///\_/\/\\\\/_/\\///__\\\_\\/_\/_/')) == [4, 2, 1, 19, 9]
list(flood_area(r'_/_\_')) == []

Input: A cross-section diagram (a string).

Output: The numbers of floods (a list/iterable of integers).

Precondition:

  • 1 ≤ len(diagram) ≤ 500

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:

(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
