### Instructions

Like an inspired Beethoven who's going to write his Moonlight Sonata, you're about to compose a colourful symphony of letters with your keyboard.
|
|
|
|
|
|
|
|
|
|
Write the function `compose`:
|
|
|
|
|
|
|
|
|
|
- Make it fire every time a key is pressed
|
|
|
|
|
- Create a new `note`, which has a background color generated using its `key`, and displays the corresponding letter pressed
|
|
|
|
|
- If the pressed key is the `Delete` one, delete the last note
|
|
|
|
|
- If the pressed key is the `Escape` one, clear all the notes
|
|
