math - What does the ^ (XOR) operator do? - Stack Overflow
Mar 6, 2021 · The truth table speaks the truth - and in conversation I usually describe XOR (eXclusive-OR, sometimes also known as EOR) as 'either A or B, but not both or neither'. – …
boolean algebra - Definition of XOR, and how to remember its …
A XOR B XOR C iff A'B'C+A'BC'+AB'C'. More importantly, can the original expression be simplified in a step-by-step manner? Personally, I feel like I would easily forget that the term …
bitwise operators - XOR from only OR and AND - Stack Overflow
Jan 17, 2011 · int bitwise_XOR(int a, int b) { return (a + b) - (a & b) - (a & b); } The reason this works is that we are doing a full add, which is equivalent to XOR when the sum for any given …
Mathematical (Arithmetic) representation of XOR - Stack Overflow
Jan 23, 2014 · (a-b)(a-b) = a 2-2·a·b + b 2 so one bit of xor gives a polynomial with 3 terms. Without floor or mod, the different bits interfere with each other, so you're stuck with looking at …
boolean - XOR operation on three values - Stack Overflow
Aug 31, 2018 · F(A,B,C) = A'B + AB'+ B'C + BC' but since. A XOR B = AB'+ A'B B XOR C = BC'+ B'C then our simplified form will be. F(A,B,C) = A XOR B + B XOR C for pseudo code …
What's the insight behind A XOR B in bitwise operation?
May 8, 2014 · What I know for A XOR B operation is that the output is 1 if A != B, and 0 if A == B. However, I have no insight about this operation when A and B are not binary. For example, if A …
How to simplify Boolean expression with XOR? - Stack Overflow
