Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.

Assume that an attacker has observed two messages C 1 and C 2 both encrypted with the same key and IV. Then knowledge of either P 1 or P 2 reveals the other plaintext since C 1 xor C 2 = (P 1 xor K) xor (P 2 xor K) = P 1 xor P 2. Many schemes require the IV to be unpredictable by an adversary. This is effected by selecting the IV at random or ...
For a symmetric matrix A, the vector vec(A) contains more information than is strictly necessary, since the matrix is completely determined by the symmetry together with the lower triangular portion, that is, the n(n + 1)/2 entries on and below the main diagonal. For such matrices, the half-vectorization is sometimes more useful than the ...
In computer programming, initialization or initialisation is the assignment of an initial value for a data object or variable. The manner in which initialization is performed depends on the programming language, as well as the type, storage class, etc., of an object to be initialized.
Unlike the bitset in C++, the Java BitSet does not have a "size" state (it has an effectively infinite size, initialized with 0 bits); a bit can be set or tested at any index. In addition, there is a class EnumSet , which represents a Set of values of an enumerated type internally as a bit vector, as a safer alternative to bit fields.
The first public release, Rust 0.1 was released on January 20, 2012 [23] for Windows, Linux, and MacOS. [24] The early 2010s saw increasing involvement from open source volunteers outside of Mozilla and outside of the United States. At Mozilla, executives would eventually employ over a dozen engineers to work on Rust full time over the next ...
Resource acquisition is initialization (RAII) [1] is a programming idiom [2] used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant , and is tied to object lifetime .
This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. Historically, BSS (from Block Started by Symbol) is a pseudo-operation in UA-SAP (United Aircraft Symbolic Assembly Program), the assembler developed in the mid-1950s for the IBM 704 by Roy Nutt, Walter Ramshaw, and others at United Aircraft Corporation.
