XOR

Read Original

This article provides an in-depth explanation of the XOR (exclusive OR) operator, starting from its boolean logic definition and truth table. It covers bitwise XOR on integers, its mathematical properties, and diverse applications in cryptography, graphics, and low-level programming (like bit swapping and the Nim game). The article also connects XOR to higher mathematical concepts such as symmetric difference, finite fields (GF(2)), and error-correcting codes.
