    Background

正在寫一個 Medium Post to Markdown 的完整轉換小工具，輸入文章連結就能自動爬取內容、下載圖片並轉換成 Markdown 格式。
Tech

爬取方式是取出 Medium 文章的前端 JSON Source，Source 會包含每個段落的資訊，將所有段落逐一爬取並轉換成 Markdown 格式。
Question

JSON Source 的段落樣式會給以下格式表示
"Paragraph": {
    "text": "code in text, and link in text, and ZhgChgLi, and bold, and I, only i",
    "markups": [
      {
        "type": "CODE",
        "start": 5,
        "end": 7
      },
      {
        "start": 18,
        "end": 22,
        "href": "http://zhgchg.li",
        "type": "LINK"
      },
      {
        "type": "STRONG",
        "start": 50,
        "end": 63
      },
      {
        "type": "EM",
        "start": 55,
        "end": 69
      }
    ]
  }
意思是 code in text, and link in text, and ZhgChgLi, and bold, and I, only i 這段文字的:
- 第 5 到第 7 字元要標示為 Code (用`Text`格式包裝)
- 第 18 到第 22 字元要標示為 URL (用[Text](URL)格式包裝)
- 第 50 到第 63 字元要標示為 Code (用*Text*格式包裝)
- 第 55 到第 69 字元要標示為 Code (用_Text_格式包裝)

第 5 到 7 & 18 到 22 在這個例子裡好處理，因為沒有交錯到；但 50-63 & 55-69 會有交錯問題，Markdown 無法用以下交錯方式表示：
code `in` text, and [ink](http://zhgchg.li) in text, and ZhgChgLi, and **bold,_ and I, **only i_

正確的組合結果如下：
code `in` text, and [ink](http://zhgchg.li) in text, and ZhgChgLi, and **bold,_ and I, _**_only i_

50-55 STRONG
55-63 STRONG, EM
63-69 EM
另外要需注意包裝格式的字串頭跟尾要能區別，Strong 只是剛好頭跟尾都是 **，如果是 Link 頭會是 [ 尾則是 ](URL)
