Hey guys im learning how to use DrRacket. I have one problem giving me trouble. Im not sure how to set up a list entered to return a min.

Im trying to create a procedure that finds the min number from the keyboard until 0 is read, and that's adds them up. Note that 0 is included in the computation.

ANY help would be great.

Thanks

(define (minimum-list x) 
(cond [(empty? (rest x)) (first x)] 
[else (min (first x) (minimum-list (rest x)))]))

 (display (minimum-list (read)))

I have this so far, but I need to be able to enter numbers without having to use paranthesis... With this code, it works, but I need to write it with paranthesis for ex. (1 3 -3).. I need it 1 3 -3


Any help would be awesome

read reads a Racket value, so the input has to be entered using Racket syntax. Since you don't want that, you should use read-line which reads a line of input (without caring how it's formatted) and returns it as a string. You can then use string-split to turn that string into a list by splitting on white space.
