## liliy 2 years ago how do i go about programming this:(JAVA) You have to put the numbers 1-8 in the eight available cells in such a way that no number borders a consecutive number, even diagonally.

I would create a map of each cell and its adjacent cells. Then make sure that the number in the cell does not have a consecutive number in any of the adjacent cells. Create a loop to try the different combinations.

you can write it as a backtracking problem - label boxes to fill from 0-7, and successively try to put a number in it: while (boxnumber < 8){ // if 8, are done ...put unused number in box ...test conditions ...if ok boxnumber += 1 // on to the next ...if not erase last try if more numbers to try, try next else backup a level, erase number there, and try next number the annoying part is keeping track of everything.
