You are given the initial state of the board and you must output a list of moves to rearrange the tiles.
Each tile is numbered from 1 to 11 (0 is the empty space). The final state is the following:
0 1 2 3 4 5 6 7 8 9 10 11
In order to make a move, you need to print the coordinate of the tile you wish to move and it will take the place of the empty space. The coordinate of a tile is the couple (row, column), with (0, 0) the top-left element.
