magic-square

Create a magic square of order three in your terminal.

"Magic square" is the name given to a square array of numbers if the sums of the numbers in each row, each column, and both main diagonals are the same; the number that each sum gives is called the "magic constant". "Order" is the number of integers along one side. (Wikipedia)

To use magic-square, you need to download the executable (.exe) file in the Releases page and use it via the command-line.

Usage
