Leet. Leet (or " 1337 "), also known as eleet or leetspeak, or simply hacker speech, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance.
Leet (or L33t) is an esoteric programming language based loosely on Brainfuck and named for the resemblance of its source code to the symbolic language "L33t 5p34k". L33t was designed by Stephen McGreal [1] and Alex Mole to be as confusing as possible. It is Turing-complete and has the possibility for self-modifying code.
An example, in English, of boustrophedon as used in inscriptions in ancient Greece (Lines 2 and 4 read right-to-left.) Boustrophedon (/ ˌbuːstrəˈfiːdən / [1]) is a style of writing in which alternate lines of writing are reversed, with letters also written in reverse, mirror-style. This is in contrast to modern European languages, where ...
In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation. It can produce either a postfix notation string, also known as Reverse Polish notation (RPN), or an abstract syntax tree (AST). [ 1 ] The algorithm was invented by Edsger Dijkstra ...

HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name.
Tree traversal. In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited.
