# A customer of UnitX is trying to identify some defects on a surface. Our neural network is 
# capable of locating the defects on an image and returns a list of points representing
# the location of the defects. E.g. [(102, 215), (109, 201), (50, 32)]

# The customer has an extra requirement where if the distance of two points are smaller than x 
# pixels, then the points should belong to the same group. Write a function that groups the list of points.

# Input:

# points (A list of tuples)

"""
The following program implements a numeric system with primitive data
structures and algorithms that can calculate derivatives for arbitrary
arithmetic expressions.

The core data structure is called `Dual`, which represents a number with its
numeric value and the operation performed in the expression AST. This means that
`Dual` remembers how the value is computed.

All primitive operations (including binary and unary) have the signature
