Therefore, the score of this matrix is 6375480. Your Cody score will be the Kurchan score of your matrix.</span></span></div></div></div>

Related to Problems 1646 and 2650, but bigger. Technically, all you need to do for this Cody problem is input a 5x5 matrix containing the numbers 1-25. However, your score will be the Kurchan value of the matrix, which is defined as the difference between the maximum and minimum of the products for the rows, columns, diagonals, and anti-diagonals of the matrix.
For example: Magic(5) is
    17    24     1     8    15
    23     5     7    14    16
     4     6    13    20    22
    10    12    19    21     3
    11    18    25     2     9
The row products are:
17 * 24 * 1 * 8 * 15=48960
23 * 5 * 7 * 14 * 16=180320
4 * 6 * 13 * 20 * 22=137280
10 * 12 * 19 * 21 * 3=143640
11 * 18 * 25 * 2 * 9=89100
The column products are:
17 * 23 * 4 * 10 * 11=172040
24 * 5 * 6 * 12 * 18=155520
1 * 7 * 13 * 19 * 25=43225
8 * 14 * 20 * 21 * 2=94080
15 * 16 * 22 * 3 * 9=142560
The diagonal products are:
17*5*13*21*9=208845
24*7*20*3*11=110880
1*14*22*10*18=55440
8*16*4*12*25=153600
15*23*6*19*2=78660
The anti-diagonal products are:
15*14*13*12*11=360360
8*7*6*10*9=30240
1*5*4*3*2=120
24*23*22*21*25=6375600
17*16*20*19*18=1860480
The highest value is 6375600, while the lowest is 120. Therefore, the score of this matrix is 6375480. Your Cody score will be the Kurchan score of your matrix.
