Suzhou numerals (蘇州碼子; also 花碼) are Chinese decimal numerals:



0 〇
1 〡 一
2 〢 二
3 〣 三
4 〤
5 〥
6 〦
7 〧
8 〨
9 〩


They pretty much work like Arabic numerals, except that when there are consecutive digits belonging to the set {1, 2, 3}, the digits alternate between vertical stroke notation {〡,〢,〣} and horizontal stroke notation {一,二,三} to avoid ambiguity. The first digit of such a consecutive group is always written with vertical stroke notation.



The task is to convert a positive integer into Suzhou numerals.



Test cases

                                        If this is an answer to a challenge…




                                        • …Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.


                                        • …Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
                                          Explanations of your answer make it more interesting to read and are very much encouraged.


                                        • …Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.



                                        More generally…




                                        • …Please make sure to answer the question and provide sufficient detail.


                                        • …Avoid asking for help, clarification or responding to other answers (use comments instead).






                                        Some of your past answers have not been well-received, and you're in danger of being blocked from answering.


                                        Please pay close attention to the following guidance:


                                        • Please be sure to answer the question. Provide details and share your research!

                                        But avoid



                                        • Asking for help, clarification, or responding to other answers.

                                        • Making statements based on opinion; back them up with references or personal experience.
