Problem: Even Fibonacci

• Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
  • 1,2,3,5,8,13,21,34,55,89...
• By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

Instructions

• Code your procedural solution into the lib/even_fibonacci.rb file.
• Code your object-oriented solution into the lib/oo_even_fibonacci.rb file.
• Run learn until you get all of the RSpec tests to pass.
