Maximum the value of a given expression for any pair of coordinates on a 2D plane | Function to find the maximum value of the given expression possible for any pair of co - ordinates.
Stores the differences between pairs.
Stores the maximum value.
Traverse the array arr [ ] [ ].
While pq is not empty and difference between point [ 0 ] and pq . top ( ) [ 1 ] > K.
Removes the top element.
If pq is not empty.
Update the value res.
Push pair { point [ 1 ] - point [ 0 ] , point [ 0 ] } in pq.
Prthe result.

How can the above be solved in Python?
 Can you provide a code to maximum the value of a given expression for any pair of coordinates on a 2D plane and the other steps required?
