| For part (a), can you explain what childSound = childSound.append(node.collect()) is doing? I can follow the rest of the code, and I understand that in the step before this, the code has just gotten the next after collecting all the children. Is this just adding the children of this node to the ones of the previous one? |
| For part (b), are the two for loops interchangeable, or does the the code need to traverse the columns before traversing the rows? |
