1410\. HTML Entity Parser
Medium
**HTML entity parser** is the parser that takes HTML code as input and replace all the entities of the special characters by the characters itself.
The special characters and their entities for HTML are:
* **Quotation Mark:** the entity is `"` and symbol character is `"`.
* **Single Quote Mark:** the entity is `'` and symbol character is `'`.
* **Ampersand:** the entity is `&` and symbol character is `&`.
* **Greater Than Sign:** the entity is `>` and symbol character is `>`.
* **Less Than Sign:** the entity is `<` and symbol character is `<`.
* **Slash:** the entity is `⁄` and symbol character is `/`.
Given the input `text` string to the HTML parser, you have to implement the entity parser.
Return _the text after replacing the entities by the special characters_.
**Example 1:**
**Input:** text = "& is an HTML entity but &ambassador; is not."
**Output:** "& is an HTML entity but &ambassador; is not."
**Explanation:** The parser will replace the & entity by &
**Example 2:**
**Input:** text = "and I quote: "...""
**Output:** "and I quote: \\"...\\""
**Constraints:**
* 1 <= text.length <= 105
* The string may contain any possible characters out of all the 256 ASCII characters.
