Write a method hash_to_pairs that takes in a hash and returns a 2D array representing each key-value pair of the hash.
def hash_to_pairs(hash) end print hash_to_pairs({"name"=>"skateboard", "wheels"=>4, "weight"=>"7.5 lbs"}) #=> [["name", "skateboard"], ["wheels", 4], ["weight", "7.5 lbs"]] puts print hash_to_pairs({"kingdom"=>"animalia", "genus"=>"canis", "breed"=>"German Shepherd"}) #=> [["kingdom", "animalia"], ["genus", "canis"], ["breed", "German Shepherd"]] puts
my code
def hash_to_pairs(hash) pair = [] hash.each do |key, value| pair << [key, value] end return pair end print hash_to_pairs({"name"=>"skateboard", "wheels"=>4, "weight"=>"7.5 lbs"}) #=> [["name", "skateboard"], ["wheels", 4], ["weight", "7.5 lbs"]] puts print hash_to_pairs({"kingdom"=>"animalia", "genus"=>"canis", "breed"=>"German Shepherd"}) #=> [["kingdom", "animalia"], ["genus", "canis"], ["breed", "German Shepherd"]] puts
