Design a function called nth-char-equal? that consumes two strings ;; and a natural and produces true if the strings both have length greater ;; than n and have the same character at position n. ;; ;; ;; Note, the signature for such a function is: ;; ;; (@signature String String Natural -> Boolean) ;; ;; ;; The tag and template for such a function are: ;; ;; (@template String) ;; ;; (define (nth-char-equal? s1 s2 n) ;; (... s1 s2 n)) (@problem 4) (@htdf nth-char-equal?) ;!!!UNCOMMENT this line when you start on this function
