a function that accepts a string as an argument, and returns a new string where streaks of consecutive characters are compressed. For example “aaabbc” is compressed to “3a2bc”.


def compress_str(str)

  new_str = ""



  i = 0

  while i < str.length

    char = str[i]

    count = 0



    while char == str[i]

      count += 1

      i += 1

    end



    if count > 1

      new_str += count.to_s + char    

    else

      new_str += char

    end

  end

  new_str


end
