#lang racket/base

;; Converts integers to English-language descriptions

;; --- NOTE -------------------------------------------------------------------
;; The test cases in "say-test.rkt" assume:
;; - Calling a function with an out-of-range argument triggers a contract error
;; - That `step3` returns a list of (number, symbol) pairs
;;
;; We have provided sample contracts so the tests compile, but you
;;  will want to edit & strengthen these.
;;
;; (For example, things like 0.333 and 7/8 pass the `number?` contract
;;  but these functions expect integers and natural numbers)
;; ----------------------------------------------------------------------------
