Edit your Bin Packing HW project according to your grader's mark ups. Be sure to fix any and all problems that your graders have discovered in your tests/functions.

We will get your submitted HW 7 files back by Friday, but until then, you can work on A2.

Problem A2:

Upgrade your Bin Packing program to full Tetris. This means whenever a tetra lands, any full rows should be eliminated and all blocks above that row should be moved down one unit.

This means you will have to write slightly more complex functions that:

1. Determine whether or not each row is full
2. Remove all the blocks from a full row, and
3. Move any higher blocks down by one

Of course, the use of helper functions is suggested, and testing is not only helpful, but required.

If you want a challenge try adding score, game pause, and/or displaying the next tetra for the player. These are all optional features, so while they may get you extra credit, they cannot make up for poorly designed/written/tested code.
