I've got this thing that has kept me puzzling for a few days now.

I've created an array of 30 integers, randomly chosen.

I would like to add the integers randomly to a two-dimensional array of 12 x 12 integers.

The remaining elements in the two-dimensional array should keep their null value.

I have no clue about how to get these integers **randomly** into the two-dimensional array, though.

Any wizzards here who would like to help me out ?
