Use proper abstract list processing functions to do following task: consumes a list of structure as its parameter and produces a list of structure whose color is equal to red.

Contract for abstract functions for list-processing:

filter: [X Boolean] [List-of X] [List-of X]

map: [X Y] [List-of X] [List-of Y]

foldr/foldl: [X Y Y] Y [List-of X] Y

Distance of two points A(x1,y1) and B(x2,y2) is given by: distance(A,B) = (x1x2 ) 2 +( y1y2 )

The code must be Dr.Racket

Must be designed in DrRacket language.
