Getting the median of 3 values using scheme's
- by kristian Roger
The problem this time is to get the median of three values (easy)
I did this:
(define (med x y z) (car(cdr(x y z)))
and it was accepted but when testing it:
(med 3 4 5)
I get this error:
Error: attempt to call a non-procedure
(2 3 4)
And when entering letters instead of number i get:
(md x y z)
Error: undefined varia
y
(package user)
Using something besides x y z I get:
(md d l m)
Error: undefined variable
d
(package user)
the question was deleted dont know how anyway
write a function that return the median of 3 values
Sorry for editing the question I got that I should put the values in order first not just a sill car and cdr thing so I did so
33> (define (med x y z)
(if(and(
(<x y) (<y z) y
if(and(
(<y x) (<x z) x z)))))
Warning: invalid expression
(if (and< (<x y) (<y z) y if (and ((<y x) (<x z) x z))))
but as u see Im getting a warning so what is wronge ?
