Solving Mixed-up Code Problems

If you see a problem like the one below you will need to put the mixed-up code in the correct order on the right side. You may need to indent the blocks as well. There may also be extra blocks that are not needed in a correct solution that you can leave on the left side. Click the “Check” button to check your solution.

See the video below for an example.
