I feel like two weeks ago i'd have struggled with part two, but I finished up your codecamp video on dynamic programing and memoization and tabulation came to mind here and saved the day :)

Saw this Ruby solution on reddit for part two as well.

c = [nil, nil, nil, 1]
a.each { |i| c[i+3] = c[i..i+2].compact.sum }
puts "Part 2: #{c.last}"
