hw_w01_d01_submission Lab work and Homework

Challenges:
I easily understood all parts of the homework except for the last part:

number_array.each { |current_index| puts get_character(message_string, current_index) }

I had to look at the method above:

def get_character(full_string, index)
  full_string[index]
end

I began to understand that "full_string" and "message_string"  was an array and that "current_index" was the index that selected a character from the array.
