In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x)
GNU Octave is a free software that helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB. It is written in C++ and has a Graphical User Interface (GUI) and an OpenGL-based graphics engine.
Learn about the basic and advanced methods of finding a pattern within a larger text, such as regular expressions, finite automata, and index methods. Compare the time and space complexity, advantages and disadvantages of different algorithms.
A string is a sequence of characters used to store human-readable or machine-readable data in computer programming. Learn about the history, types, length, encoding and operations of strings in different programming languages.
Its length is n. P denotes the string to be searched for, called the pattern. Its length is m. S[i] denotes the character at index i of string S, counting from 1. S[i..j] denotes the substring of string S starting at index i and ending at j, inclusive. A prefix of S is a substring S[1..i] for some i in range [1, l], where l is the length of S.
