Hello, I am trying to write a program in the Scheme language. what program does is that it outputs how many times letter g appears in string. in this case, as you can see it appears 2 times. the code that I have so far is given below however it does not compiles and I do not know what to do with it. I am new in this language and need help to complete so it can work.

Thanks

(define String( "Scheme is fun language" )) (define count 0) ;create a variable to store the number of count (define (search t) (if (= (length(t)) 0)) count (= g (car t)) ( set! count (+ count 1)) ;else statement that increment the number of count if the car is letter d (search (cdr t)) ) ;recursive call
