hi

i have an n*n page (n is a power of 2) with an empty place in it, and i want to fill in this sqaure with right trominos (a tromino has an 'L' shape)

i want to show the empty spaces with zeros and the ones filled with trominos with ones.

everytime a tromino is placed in the sqaure page, the page must be displayed on teh monitor with the 0s and 1s.

I am really stuck on this.....i'd be very happy for any help

many thanks in advance
