[racket] Exercise 76

From: Matthias Felleisen (matthias at ccs.neu.edu)

Here is a start: 

(define-struct editor [text index])
;; An Editor is a structure: 
;;   (make-editor String Number)
;; interpretation: (make-editor t i) means that the editor currently contains the text t and that the cursor sits between the i-th and the (i+1)-st character in t.

Q1: Why don't you show us your data example so that we can see whether you are on the right track? 
Q2: Challenge: What conditions must i satisfy for the interpretation to make sense?
