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 … Prikaži več Conventional swapping requires the use of a temporary storage variable. Using the XOR swap algorithm, however, no temporary storage is needed. The algorithm is as follows: Since XOR is a Prikaži več The binary operation XOR over bit strings of length $${\displaystyle N}$$ exhibits the following properties (where $${\displaystyle \oplus }$$ denotes XOR): • L1. Commutativity: $${\displaystyle A\oplus B=B\oplus A}$$ • L2. Associativity: Prikaži več On modern CPU architectures, the XOR technique can be slower than using a temporary variable to do swapping. At least on recent x86 CPUs, both by AMD and Intel, moving … Prikaži več On architectures lacking a dedicated swap instruction, because it avoids the extra temporary register, the XOR swap algorithm is required for optimal register allocation. This is particularly important for compilers using static single assignment form for … Prikaži več A C function that implements the XOR swap algorithm: The code first checks if the addresses are distinct. Otherwise, if they were equal, the algorithm would fold to a triple *x ^= *x resulting in zero. The XOR swap … Prikaži več The underlying principle of the XOR swap algorithm can be applied to any operation meeting criteria L1 through L4 above. Replacing XOR by addition and subtraction gives various slightly different, but largely equivalent, formulations. For example: Unlike the XOR … Prikaži več • Symmetric difference • XOR linked list • Feistel cipher (the XOR swap algorithm is a degenerate form of a Feistel cipher) Prikaži več
Swap two numbers using Bitwise XOR Operator - Algorithms
Spletgocphim.net Splet16. nov. 2024 · The task is to swap the values of both the variables without using third variable. Examples: X : 10 Y : 20 After swapping X and Y, we get : X : 20 Y : 10 A : 'Hello' B : 'World' After swapping A and B, we get : A : 'World' B : 'Hello' Method 1 :- Using simple built-in method left , right = right , left signcryption algorithm
