一、Magic Squares

      A magic square of order n is an arrangement of n×n numbers, usually distinct integers, in a square, such that the n numbers in all rows, all columns, and both diagonals sum to the same constant (see Wikipedia: Magic Square).

You are to write a Java program (MagicSquare.java) for checking the row/column/diagonal values of a matrix and then judging whether it is a magic square.
