Find the maximum value in the primary diagonal of the array
Find the minimum value in the secondary diagonal of the array
Change the values ABOVE the primary diagonal to be all ZEROs
Change the values BELOW the primary diagonal to be all ZEROs
Swap the values of the first column with the values of the third column
Swap the values of the second row with the values of the fourth row
