How to trim std::string is able to stores multiple '\0'.

The std::string is able to stores multiple '\0'

Trimming a std::string that contains multiple null characters ('\0') can be a bit tricky because std::string can store null characters within it. To effectively trim such a string, you need to handle these null characters explicitly. Here’s how you can do it:

Steps: Remove Leading Null Characters: Iterate through the string from the beginning to remove any leading null characters.

Remove Trailing Null Characters: Iterate from the end of the string to remove any trailing null characters.

Trim Inner Null Characters: Optionally, if you want to remove null characters from the middle of the string as well, you can replace them with an empty string.
