Given a string A representing an absolute path for a file (Unix-style).
Return the string A after simplifying the absolute path.Note
In Unix-style file system:
- A period '.' refers to the current directory.
- A double period '..' refers to the directory up a level.
- Any multiple consecutive slashes '//' are treated as a single slash '/'.
In Simplified Absolute path:
- The path starts with a single slash '/'.
- Any two directories are separated by a single slash '/'.
- The path doesn't end with trailing slashes '/'.
- The path only contains the directories on the path from the root directory to the target file or directory (i.e., no period '.' or double period '..')
- The path will not have whitespace characters.
