Pushing numbers (Posted on 2007-02-12)

You need to make it so that all the numbers from 1 to 6 appear once in every row and column. You can only do that by "pushing" the rows down and the columns left. Each time you "push" a row or a column all the numbers in it move 1 block to the direction you have pushed it.

	1	3	6	2	5

	4	6	4	1	5	1

	3	2	5	2	6	3

	5	2	6	1	4	4

	4	6	3	4	3	2

	1	5	2	6	5	1

3

Can you complete the grid?

The positions after each move are:

1 3 6 2 5 4 6 4 1 5 1 3 2 5 2 6 3 5 2 6 1 4 4 4 6 3 4 3 2 1 5 2 6 5 1 3
