1) What is the difference between a shallow copy and a deep copy?
Shallow Copy stores the references of objects to the original memory address.
Deep copy stores copies of the object's value.
Shallow Copy reflects changes made to the new/copied object in the original object.
Deep copy doesn't reflect changes made to the new/copied object in the original object.
Shallow Copy stores the copy of the original object and points the references to the objects.
Deep copy stores the copy of the original object and recursively copies the objects as well.
Shallow copy is faster.
Deep copy is comparatively slower.
