Here is an example of a function that sums all of the numbers from zero to the parameter, n . (define (sum n) (if (zero? n) 0 (+ n (sum (sub1 n))))) http://duoduokou.com/cplusplus/40876474003208690366.html

WebThe syntaxof a Racket addition expression is: (+ e1e2) Here, e1and e2are expressions. For example, we could write (+ 251251)and we could also write (+ (+ 240251)(+ 235301))or even (+ #t251). The parentheses are mandatory. Racket uses prefixnotation, where operators in expressions like addition are written before their operands rather than between. WebTail recursion has special status in Racket because the compiler notices tail calls and optimizes them. Ordinarily, each call to a function, including a recursive call, causes …
