For example, in Java, any class that implements the Comparable interface has a compareTo method which either returns a negative integer, zero, or a positive integer, or throws a NullPointerException (if one or both objects are null). Similarly, in the .NET framework, any class that implements the IComparable interface has such a CompareTo method.
A more complex example is the lexer hack in C, where the token class of a sequence of characters cannot be determined until the semantic analysis phase since typedef names and variable names are lexically identical but constitute different token classes. Thus in the hack, the lexer calls the semantic analyzer (say, symbol table) and checks if ...
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
For example, the lexicographically minimal rotation of "bbaaccaadd" would be "aaccaaddbb". It is possible for a string to have multiple lexicographically minimal rotations, but for most applications this does not matter as the rotations must be equivalent. Finding the lexicographically minimal rotation is useful as a way of normalizing strings
In mathematics, the lexicographic or lexicographical order (also known as lexical order, or dictionary order) is a generalization of the alphabetical order of the dictionaries to sequences of ordered symbols or, more generally, of elements of a totally ordered set. There are several variants and generalizations of the lexicographical ordering.
translating collocations, phrases and examples in bi- and multilingual dictionaries; designing the best way in which users can access the data in printed and electronic dictionaries; One important goal of lexicography is to keep the lexicographic information costs incurred by dictionary users as low as possible. Nielsen (2008) suggests relevant ...
Instead, East Windsor police personally visited Vaughn at the Windsor Hotel where he was staying, and warned him to stop making the calls. The warning came after Vaughn’s first few attempts.
Lexicographic max-min optimization is a variant of lexicographic optimization in which all objectives are equally important, and the goal is to maximize the smallest objective, then the second-smallest objective, and so on. In game theory, the nucleolus is defined as a lexicographically-minimal solution set. [6]
