Proper … Web30 May 2015 · The definition of equality between two sets A and B is: A = B <=> A is a subset of B and B is a subset of A The Racket version is: (define (set-equal? A B) (and (subset A B) (subset B A))) However for finite sets we can do better (in terms of speed): For finite sets: A = B <=> A is a subset of B and size (A) = size (B) And in Racket: proactive care wellness center greenville sc
