19. Lo Shu Magic Square The Lo Shu Magic Square is a grid with 3 rows and 3 columns, shown in Figure 7-31. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 through 9 exactly. The sum of each row, each column, and each diagonal all add up to the same number.

int[][] magicArray = { {4, 9, 2},

{3, 5, 7},

{8, 1, 6} };

int[][] normalArray = { {1, 2, 3},

{4, 5, 6},

{7, 8, 8} };

It's good practice to use one method to complete one task. For example, A checkRange method accepts a two-dimensional int array as an argument, and returns true if the values in the list are within the specified range (1-9). Otherwise, it returns false. A checkUnique method accepts a two-dimensional int array as an argument, and returns true if the value in the array are unique (no repetitive number). Otherwise, it returns false.

In a program you can simulate a magic square using a two-dimensional array. Write a method that accepts a two-dimensional array as an argument, and determines whether the array is a Lo Shu Magic Square. Test the function in a program.
