-/**
- * 71. Simplify Path
-
- Given an absolute path for a file (Unix-style), simplify it.
-
- For example,
- path = "/home/", => "/home"
- path = "/a/./b/../../c/", => "/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/".
- In this case, you should ignore redundant slashes and return "/home/foo".
