[chry44]

does anyone know how to write a function that organize an array like this?:
for example:

18 9   20 7  90
65 4   77 83 32
2  34  12 20 11
22 23  10 89 57
1  28  55  0 99

becomes:

0  1  4  10 20
2  7  11 20 32
9  12 22 34 65
18 23 55 77 89
28 57 83 90 99

The array is sorted along the diagonals starting upper left and proceeding to lower right.

Step 1 is to sort the array in ascending sequence.
Step 2 is to arrange the values in the correct display position.

I would use a mask array to do this:

0 1 5 6 10 11 etc...

Step 3 display the sorted array according to the mask:
arr[0], arr[1], arr[5]. arr[6], arr[10], arr[11], etc...

You can create the display in rows inside the display function. What you see on the screen does not have to match what is in memory.
