;; Function to convert a number to an alphanumeric string (hexadecimal representation)
(define (number-to-alphanumeric n)
(number->string n 16))
;; Function that takes a prime and a second number, multiplies them, and outputs an alphanumeric string
(define (multiply-and-convert prime second-number)
(let ([product (* prime second-number)])

;; New function that iterates through numbers up to a given total,
;; calls multiply-and-convert for each, and outputs seed number and alphanumeric string
(define (generate-and-output prime total)
(for ([i (in-range 1 (add1 total))]) ; iterate from 1 to total inclusive
(let ([alphanumeric-string (multiply-and-convert prime i)])
(printf "Seed Number: ~a, Alphanumeric String: ~a\n" i alphanumeric-string))))
;; Example usage
(define prime-number 197) ; Example prime number
(define total 100) ; Total numbers to generate
;; Call the function to generate and output results
(generate-and-output prime-number total)
Write, Run & Share Racket code online using OneCompiler's Racket online compiler for free. It's one of the robust, feature-rich online compilers for Racket language, running on the latest version 6.8. Getting started with the OneCompiler's Racket compiler is simple and pretty fast. The editor shows sample boilerplate code when you choose language as Racket and start coding.
OneCompiler's Racket online editor supports stdin and users can give inputs to programs using the STDIN textbox under the I/O tab. Following is a sample Racket program which takes name as input and print your name with hello.
#lang racket/base
(define name (read))
(printf "Hello ~a.\n" name)
Racket is a general-purpose programming language based on the Scheme dialect of Lisp. It is also used for scripting, computer science education, and research related applications.

If, If-else are used when you want to perform a certain set of operations based on conditional expressions.
(if cond-expr then-expr)
(if cond-expr then-expr else-expr)
For loop is used to iterate a set of statements based on a condition.
(for (for-clause ...) body-or-break ... body)
where
for-clause = [id seq-expr] | [(id ...) seq-expr] | #:when guard-expr | #:unless guard-expr | break-clause
break-clause = #:break guard-expr | #:final guard-expr
body-or-break = body | break-clause
seq-expr : sequence?
A lambda expression is used to create a function.
(lambda (argument-id ...)
body ...+)
