Consider the entire hierarchy of The Revengers. Apply the Composite design pattern to the hierarchy like:

Level $1$: The Revengers,

Level $2$: The Magician, Avon The Slayer and Manic the Mayhem.

Level $3($actions$)$: The Magician $($Disappear$,$ Fly$),$ Avon The Slayer $($Fight$),$ Manic The Mayhem $($Run fast, Unbreakable$).$

You can refer to the following $3$ steps for implementing the solution:

$1.$ Create the Abstract class which initialises the superhero list

$2.$ Create a directory which implements the abstract class which adds a particular superhero to the directory

$3.$ Create the Composite pattern class which has the main class that takes the input for the $3$ levels of abstraction
