NAME

Math::MagicSquare - Magic Square Checker

SYNOPSIS

use Math::MagicSquare;

$a= Math::MagicSquare -> new ([num,...,num],
                               ...,
                              [num,...,num]);
$a->print("string");
$a->check;

DESCRIPTION

The following methods are available:

new

Constructor arguments are a list of references to arrays of the same length.

$a = Math::MagicSquare -> new ([num,...,num],
                                ...,
                               [num,...,num]);

check

This function can return 3 value

  • 0: the Square is not Magic

  • 1: the Square is a Semimagic Square (the sum of the rows and the columns is equal)

  • 2: the Square is a Magic Square (the sum of the rows, the columns and the diagonals is equal)

print

Prints the Square on STDOUT. If the method has additional parameters, these are printed before the Magic Square is printed.

EXAMPLE

   use Math::MagicSquare;

   $A = Math::MagicSquare -> new ([8,1,6],
                                  [3,5,7],
                                  [4,9,2]);
   $A->print("Magic Square A:\n");
   $i=$A->check;
   if($i == 2) {print "This is a Magic Square.\n";}

This is the output:
   Magic Square A:
       8     1     6 
       3     5     7 
       4     9     2 
   This is a Magic Square.
