File Path Simplification

Function Name: simplifyPath

Description

Implement a function that takes a string representing an absolute file path in a Unix-style file system, and returns the simplified canonical path. In a Unix-like operating system, a canonical path is the simplest absolute path that points to the same location as the original path.

A canonical path has the following properties:

- The path starts with a single slash ('/').

- Any two directories are separated by a single slash ('/').

- The path does not end with a trailing '/'.

- The path only contains the directories on the path from the root directory to the target file or directory, with the exception of '.' or '..' which are interpreted as current and parent directory respectively.

Requirements

• The input path will be a non-empty string of characters.
• The simplifyPath function should take a single string parameter representing the file path to simplify.
• The function should return the simplified canonical path as a string.
• The simplified path must not contain any '.' or '..' elements.
• Consecutive slashes ('//') should be reduced to a single slash ('/').
• If the path refers to the root directory, the return value should be '/'.

Examples

simplifyPath('/home/') returns '/home'simplifyPath('/../') returns '/'simplifyPath('/home//foo/') returns '/home/foo'simplifyPath('/a/./b/../../c/') returns '/c'simplifyPath('/a/../../b/../c//.//') returns '/c'
