… Can you give me more hint about (1) copy the value in the tree?
I think it cannot be copied because V doesn't have Copy trait.

- yes, you can leave empty nodes as is.
- You need to (1) copy the value in the tree, (2) forget about the value in the tree, and (3) return the copied value. Does it help you..?

Could you, please, explain, what does "(2) forget about the value in the tree" mean? Thank you!
