You're on a rectangular mined icefield: when you go in one direction, you slide on the ice until you're stopped by a rock, the end of the icefield, or some rough spot. But you're here for a good reason, there are gems on the icefield: you have to find any route to collect them all, avoiding the mines.
The icefield will be represented by a tuple of strings. Gems will be represented by '$', rocks by 'X', mines by '*', ice by ' ' and rough spots by '.'.
You can go in all eight directions: northwest 'NW', north 'N', northeast 'NE', west 'W', east 'E', southwest 'SW', south 'S', southeast 'SE'.
Dead route (you're stuck): ['SE', 'E', 'SE'] Possible route: ['SE', 'E', 'W', 'NW', 'N', 'S', 'SW', 'S', 'S', 'NE', 'E', 'SE', 'E', 'N', 'SW', 'NW', 'NW', 'SE', 'NE', 'NW', 'E', 'NE', 'N'] grid = (' .$*.X*X*$', start = (0, 1) '.X$** X X$', ' *.$ *X..X', '*.*. $XX$X', ' . X.* .', ' .*X.X$*$X', '.$$ .*.X$', '*$*.*X$$$ ')
Input: A tuple of strings and a tuple of two ints.
Output: An iterable of strings.
list(checkio((' .$*.X*X*$', '.X$** X X$', ' *.$ *X..X', '*.*. $XX$X', ' . X.* .', ' .*X.X$*$X', '.$$ .*.X$', '*$*.*X$$$ '), (0, 1))) = ['SE', 'E', 'W', 'NW', 'N', 'S', 'SW', 'S', 'S', 'NE', 'E', 'SE', 'E', 'N', 'SW', 'NW', 'NW', 'SE', 'NE', 'NW', 'E', 'NE', 'N']
- You can collect all gems in any possible order (otherwise it would be far more difficult).
- Given puzzles are solvable.
- 5 ≤ len(grid) ≤ 50 and 5 ≤ len(grid) ≤ 50.
- all(len(row) == len(grid) for row in grid).
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
