Checkers Capture
Imagine a n-by-n chessboard, where your single checker currently stands at position (x, y) and there is pieces - a list that contains the positions of the opponent’s pawns.
Your checker may capture a piece only one step in the four diagonal directions assuming that the square behind the opponent piece in that diagonal direction is vacant. Your checker can then capture that piece by jumping over it into the vacant square, immediately removing that captured piece from the board. The chain of captures continues from the new square, potentially capturing all the pieces in one swoop.
Your function should return the maximum number of pieces that your checker could potentially capture in a single move.
Input: Three arguments: size (number), coordinates (array of two integers (number)) and a sequence of opponent's pieces (array of coordinates).
Output: Integer (number).
Examples:
assert.strictEqual( maxCheckersCapture( 5, [0, 2], [ [1, 1], [3, 1], [1, 3], ] ), 2 ); assert.strictEqual( maxCheckersCapture( 7, [0, 0], [ [1, 1], [1, 3], [3, 3], [2, 4], [1, 5], ] ), 3 ); assert.strictEqual( maxCheckersCapture( 8, [5, 3], [ [6, 2], [2, 4], [2, 2], [0, 4], [5, 5], [1, 5], [3, 7], [6, 4], [5, 7], [0, 6], [0, 2], [1, 7], [2, 6], [6, 0], [6, 6], [3, 5], ] ), 1 );
The mission was taken from Python CCPS 109. It is taught for Ryerson Chang School of Continuing Education by Ilkka Kokkarinen
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=js 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.
