Simplify Path questioneditorial Solution

Given an absolute path for a file (Unix-style), simplify it.

For example,
Path = "/home/" , = ="/home"
Path = "/a/./b/../../c/" , = ="/c"

Path = "/a/./b/../c/" , = ="/a/c"

path = "/a/./b/c/", => "/a/b/c"

Corner Cases:

• Did you consider the case where path = "/../" ?
  In this case, you should return "/" .
• Another corner case is the path might contain multiple slashes ‘/‘ together, such as "/home//foo/" .
  Should ignore redundant slashes and return"/home/foo".
