In computing, the working directory of a process is a directory of a hierarchical file system, if any, [nb 1] dynamically associated with the process. It is sometimes called the current working directory (CWD), e.g. the BSD getcwd [1] function, or just current directory. [2]
A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure. It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
The reason for this is the fact that paths are easier to be queried when it comes to level ancestor queries. Consider a path P consisting of n nodes rooted at a node r. We can store the path into an array of size n called Ladder and we can quickly answer a level ancestor query of LA(v, d) by returning Ladder[d] if depth(v)≤d. This will take O ...
The path separator is > on Multics, [5] / on Unix-like systems, [6] and \ on MS-DOS 2.0 and later, Windows, and OS/2 systems. An absolute path begins at the root directory; that is, begins with a path separator character, which, at the beginning of a path, represents the root directory. A path consisting only of a path separator character ...
Windows 7 and Vista support a maximum of 31 reparse points (and therefore symbolic links) for a given path (i.e. any given path can have at most 31 indirections before Windows gives up). [18] Only users with the new Create Symbolic Link privilege, which only administrators have by default, can create symbolic links. [ 19 ]
Python's syntax is simple and consistent, adhering to the principle that "There should be one— and preferably only one —obvious way to do it." The language incorporates built-in data types and structures, control flow mechanisms, first-class functions , and modules for better code reusability and organization.

The number of edges along the shortest path between two nodes. Level The level of a node is the number of edges along the unique path between it and the root node. [4] This is the same as depth. Width The number of nodes in a level. Breadth The number of leaves. Forest A set of one or more disjoint trees. Ordered tree
