[2020-03-09] Challenge #383 [Easy] Necklace matching
;; [2020-03-09] Challenge #383 [Easy] Necklace matching
;;
;; Imagine a necklace with lettered beads that can slide along the
;; string. Here's an example image. In this example, you could take
;; the N off NICOLE and slide it around to the other end to make
;; ICOLEN. Do it again to get COLENI, and so on. For the purpose of
;; today's challenge, we'll say that the strings "nicole", "icolen",
;; and "coleni" describe the same necklace.
;;
;; Generally, two strings describe the same necklace if you can remove

; - Changing R12/R13 takes affect only when C4=C9=0, but should be set
; when C4>0 for compatibility reasons.
; - Changing R4 takes effect as long as C4 > R4' (new value).
; - Vsync starts when C4=C7
