Problem Statement

Quite often one needs loops which, in the last iteration, execute only part of the loop body. Demonstrate the best way to do this. Write a loop which writes the comma-separated list using separate output statements for the number and the comma from within the body of the loop.

Let's start with the solution:

#lang racket
(for ((i (in-range 1 15)))
  (display i)
  #:break (= 10 i)
  (display ", "))
