listmaker.rb

# Create a test for a method`make_list` that takes an array and returns that same array but
# as an array of strings in a numbered list.

# Run this test by typing `rspec list_maker_spec.rb` in your terminal.

# Then, create a method on array called `make_list` that iterates over the array it is
# called with and appends a number, a period, and a space to each element.

# e.g make_list(["ich", "ni", "san"]) #=> ["1. ich", "2. ni", "3. san"]
