With these 2 blocks, we cover from 384-767. If we keep repeating the same procedure for

the other blocks, we get the commands in the following table. In some of the cases, the

blocks need to be divided into smaller blocks. In our example, instead of having a single block

of 4, we used 2 x 2 blocks: one at the start (classifier 2) and one at the end (classifier 8).
