Problem 46600. Generate a list of composite numbers
Prime numbers get a lot of attention in Cody, while composite numbers get relatively little. Right now a search for "prime" on Cody yields 153 problems, while a search for "composite" yields only 27--and only eight of those deal with composite numbers. Let's work toward restoring the balance.
Write a function to list the composite numbers less than or equal to the input number. Remember that 1 is neither prime nor composite.
