soz but i dono understand wat you sed. lol!!!!!!!!!!!!
dont matter cuz ill cum back to it wen i no more. >:)
Maybe ill have bteere luck with dis kwestshun :)
im stuk on prob 2.58 in SCIP
not part a of the prob. dat part i jus bunged the '+ symbol
in da middl to get constructors like
(define (make-sum a1 a2) (list a1 '+ a2))
but part b has meh pissed!!!! nd if yu piss me off yued bteere
run far cause my rage nd anger is reantles. lol!!!!!!!!!!!
I thought that I cud use a backtrack procedure like
1. find a '* symbol
2. backtrack one item
3. bung a '( before it
4. fast forward one item and bung a ') after it
so the expression
x + 3 * (x + y)
x + (3 * (x + y))
but that dont wrk. any 1 with any helpful hints
bye peeps ttyl
