Learn how to write FP code that displays a graphical representation of all the numerous N-Queens solutions for N=4,5,6,7,8.
See how to neatly solve the problem by exploiting its self-similarity and using a divide and conquer approach.
See how to write the equivalent Haskell program using the Gloss graphics library.
Make light work of assembling multiple images into a whole, by exploiting Doodle’s facilities for combining images using a relative layout.
See relevant FP functions, like Foldable’s intercalate and intersperse, in action.
