Problem: Multiples of 3 and 5

  • If we list all of the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6, and 9. The sum of these multiples is 23.
  • Find the sum of all the multiples of 3 or 5 below 1000.

Instructions

  • Code your procedural solution into the lib/multiples.rb file.
  • Then when you have finished the procedural solution, code your object-oriented solution into the lib/oo_multiples.rb file.
  • Run learn until you get all of the RSpec tests to pass.
