A data structure known as a hash table.. In computer science, a data structure is a data organization, and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
Computer science. Computer science is the study of computation, information, and automation. [ 1][ 2][ 3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software ). [ 4][ 5][ 6] Algorithms and data ...
Structure and Interpretation of Computer Programs ( SICP) is a computer science textbook by Massachusetts Institute of Technology professors Harold Abelson and Gerald Jay Sussman with Julie Sussman. It is known as the "Wizard Book" in hacker culture. [ 1] It teaches fundamental principles of computer programming, including recursion ...
t. e. Advanced Placement ( AP) Computer Science A (also known as AP CompSci, AP CompSci A, APCSA, AP Computer Science Applications, or AP Java) is an AP Computer Science course and examination offered by the College Board to high school students as an opportunity to earn college credit for a college -level computer science course.
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. Second, Boolean algebra uses logical operators such ...
Computer-based test: Multiple times a year (depends on availability of the test center) Paper-based test: Up to 3 times a year in October, November and February [2] Restrictions on attempts: Computer-based test: Can be taken only once after 21 days from the day of exam in every year. Maximum of 5 times a year.
An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. [ 1][ 2][ 3] The simplest type of data structure is a linear array, also called one-dimensional array. For example, an array of ten 32-bit (4-byte) integer variables, with indices 0 through 9, may be stored as ten words at ...
Information retrieval ( IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text or other content-based indexing.
