In computerscience and mathematical logic , an alphabet is a finite set of symbol s or letters , e.g. characters or digits. The most common alphabet is 0,1 , the binary alphabet . A finite Stringcomputersciencestring is a finite sequence of letters from an alphabet for instance a binary string is a string drawn from the alphabet 0,1 . An infinite Infinite sequence Infinite sequences in theoretical computerscience sequence of letters may be constructed from elements of an alphabet as well. Given an alphabet math Sigma math , we write math Sigma math to denote the set of all finite strings over the alphabet math Sigma math . Here, the math math denotes the Kleene star operator. We write math Sigma infty math or occasionally, math Sigma N math or math Sigma omega math to denote the set of all infinite sequences over the alphabet math Sigma math . For example, if we use the binary alphabet 0,1 , the strings , 0, 1, 00, 01, 10, 11, 000, etc. would all be in the Kleene closure of the alphabet where represents the empty string Alphabets are important in the use of formal languages , Automata theory automata and semiautomaton semiautomata . In most cases, for defining instances of automata, such as deterministic finite automaton deterministic finite automata DFAs , it is required to specify an alphabet from which the input strings for the automaton are built.

Divisions There are four divisions in ACSL Classroom, Junior, Intermediate, and Senior. Junior is recommended for middle school students no students above the ninth grade may compete in it . Intermediate and Senior divisions are for secondary school students, Intermediate being easier and Senior being more difficult. At the All Star final competition, the Junior teams consist of 5 members each while the Senior and Intermediate teams can consist of 3 or 5 members. Each team competes against other same sized teams in its division. Preliminary Competition The preliminary competition, in which individual students compete to get their school team qualified for the All Star competition, consists of four rounds.

In computer programming , a rope also known as cord is a heavyweight stringcomputersciencestring , involving the use of a concatenation tree representation.

A node in the tree has a left child and a right child the left child is the first part of the string, while the right child is the final part of the string. Concatenation of two ropes simply involves the creation of a new tree node with both ropes as children. To ensure logarithmic time indexing and sub string operations the resulting rope may need to be balanced. Various balancing strategies are possible. The main advantages of ropes as compared to storing strings as character arrays is that they enable much faster concatenation than ordinary strings, and don t require a large contiguous memory space to store a large string. The main disadvantages are greater overall space usage and slower indexing, both of which become more severe ...

For other meanings of the term terminal value , see Terminal value disambiguation . In computerscience , a terminal value is a string or character representing the end. eg, a terminal value is introduced when one hits the enter key in order to start a new paragraph. Terminal value may also refer to a symbol of a grammar definition from Backus Naur form . A terminal value in Bakus Naur form is the name of a symbol that never appears on the left hand side of the grammar list. For example br top node node1 node2 br node1 hello goodbye br node2 Dave James br Here the symbols hello , goodbye , Dave and James are the terminal symbols, i.e. the bottom level of the grammar, what you actually see.

A production or production rule in computerscience is a rewrite rule specifying a symbol substitution that can be recursively performed to generate new symbol sequences. A finite set of productions math P math is the main component in the specification of a formal grammar specifically a generative grammar . The other components are a finite set math N math of nonterminal symbol s, a finite set known as an alphabet math Sigma math of terminal symbol s that is Disjoint sets disjoint from math N math and a distinguished symbol math S in N math that is the start symbol. In an unrestricted grammar , a production is of the form math u to v math where math u math and math v math are arbitrary strings of terminals and nonterminals however math u math may not be the empty string. If math v math is the empty string, this is denoted by the symbol math epsilon math , or math lambda math rather than leave the right hand side blank . So productions are of the form math N cup Sigma N N cup Sigma to N cup Sigma math Where math math is the Kleene plus operator, math math is the Kleene star operator, and math cup math denotes union set theory set union . The other types of formal grammar in the Chomsky hierarchy impose additional restrictions on what constitutes a production. Notably in a context ... are of the form math N to N cup Sigma math Grammar generation To generate a string in the language, one begins with a string consisting of only a single start symbol , and then successively applies the rules any number of times, in any order to rewrite this string.

nofootnotes date September 2010 In computerscience , a Predicate mathematical logic predicate is called an invariant to a sequence of Operation mathematics operations provided that if the predicate is true before starting the sequence, then it is true at the end of the sequence. Use Although computer program s are typically mainly specified in terms of what they change, it s equally important to know or specify the invariants of a program. This is especially useful when reasoning about the program. The theory of optimizing compiler s, the methodology of design by contract , and formal methods for determining program correctness , all pay close attention to invariant s in computer program s. Programmers often make use of Assertion computing assertions in their code to make invariants explicit. Some object oriented programming language s have a special syntax for specifying class invariant s. Example The MU puzzle is a good example of a logical problem where determining an invariant is useful. The puzzle is as follows If a string ends with an I, a U may be appended x I x IU Any string after an M may be completely duplicated M x M xx Any three consecutive I s III may be replaced with a single U x III y x U y Any two consecutive U s may be removed x UU y xy Is it possible to convert MI into MU using these four transformation rules only?
