There are four substring missions that were born all in one day and you shouldn’t be needed more than one day to solve them. All of those mission can be simply solved by brute force, but is it always the best way to go? (you might not have access to all of those missions yet, but they are going to be available with more opened islands on the map).
A very similar to the first is the second mission of the series with only one distinction is that you should look in a completely different way. You need to find the first longest substring with all unique letters. For example, in substring "abca" we have two substrings with unique letters "abc" and "bca", but we should take the first one, so the answer is "abc".
Input: String (str).
Output: String (str).
assert non_repeat("aaaaa") == "a" assert non_repeat("abdjwawk") == "abdjw" assert non_repeat("abcabcffab") == "abcf"
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
