6. Long Press on a shape, will delete that shape
7. Deletion can be undone
8. Stats screen shows count of all shapes

About UI I have tried to create minimal UI, focussing more on code functionality , simplicity and architecture.

About Data Structures Used 'LinkedList' of Shape objects to suit the required functionalities and minimize time and space complexity.
