A magic square is an arrangement of distinct integers, in a square grid,
where the numbers in each row, and in each column, and the numbers in the forward and backward main diagonals,
all add up to the same number.
Domino tiles contain two numbers from 0 (empty) to 6. Tiles are unordered and 1-6 is the same as 6-1. The double-six set contains 28 unique tiles - all combinations of number pairs.
You are given a size for the magic square and a number . You should build a magic square to the given size so that the sum of the horizontal and vertical diagonals equal the given number . You can place domino tiles from double-six set only vertically and they should be unique .
Here is example for size = 4 and number = 5:
The result magic square should be represented as a list/tuple of lists/tuples with integers.
Input: Two arguments. A magic square size and a number as integers
Output: The magic square as a list/tuple of lists/tuples with integers.

How it is used: This is a constraint satisfaction problem. It's used not only for solving games of solitaire, but also for planning and resource allocation in city planning, construction and just about anything else.

All input test cases are solvable.
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
