  2. Bit manipulation - Wikipedia

    en.wikipedia.org/wiki/Bit_manipulation

    There's no simple programming language idiom, so it must be provided by a compiler intrinsic or system library routine. Without that operator, it is very expensive (see Find first set#CLZ) to do any operations with regard to the high bit of a word, due to the asymmetric carry-propagate of arithmetic operations. Fortunately, most cpu ...

  3. Comparison of programming languages (list comprehension)

    en.wikipedia.org/wiki/Comparison_of_programming...

    List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.

  4. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.

  5. XOR swap algorithm - Wikipedia

    en.wikipedia.org/wiki/XOR_swap_algorithm

    In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required. The algorithm is primarily a novelty and a way of demonstrating properties of the exclusive or operation.

  6. Exclusive or - Wikipedia

    en.wikipedia.org/wiki/Exclusive_or

    ^, the caret, has been used in several programming languages to denote the bitwise exclusive or operator, beginning with C [20] and also including C++, C#, D, Java, Perl, Ruby, PHP and Python.

  7. Logical disjunction - Wikipedia

    en.wikipedia.org/wiki/Logical_disjunction

    Disjunction is often used for bitwise operations. Examples: 0 or 0 = 0; 0 or 1 = 1; 1 or 0 = 1; 1 or 1 = 1; 1010 or 1100 = 1110; The or operator can be used to set bits in a bit field to 1, by or-ing the field with a constant field with the relevant bits set to 1. For example, x = x | 0b00000001 will force the final bit to 1, while leaving ...

  8. Josephus problem - Wikipedia

    en.wikipedia.org/wiki/Josephus_problem

    The easiest way to find the safe position is by using bitwise operators. In this approach, shifting the most-significant set bit of n to the least significant bit will return the safe position. [11] Input must be a positive integer. n = 1 0 1 0 0 1 n = 0 1 0 0 1 1

  9. XOR linked list - Wikipedia

    en.wikipedia.org/wiki/XOR_linked_list

    An XOR linked list is a type of data structure used in computer programming. It takes advantage of the bitwise XOR operation to decrease storage requirements for doubly linked lists by storing the composition of both addresses in one field.
