;;-- 1..9
;;(setq numbers (sequence 1 9))
;;-- 4096..5104
(setq numbers (sequence 4096 5104))
;;-- determine the middle
(setq middle (numbers 4))
;;-- calculate the sum
(setq sum (add (numbers 0) (numbers -1) middle))
;;-- listy 3x3 square
(setq s '( () () () ))
;;-- solve
(push middle (s 1))
(push (numbers 0) (s 0))
(push (numbers -1) (s 2))
(push (numbers 1) (s 2) -1)
(push (numbers -2) (s 0))
(push (numbers 2) (s 1))
(push (numbers -3) (s 1) -1)
(push (numbers 3) (s 2))
(push (numbers -4) (s 0) -1)
;;-- display
(println "The Magic = " sum)
(map println (map string s))
