SpletTo understand this trick, break the statements into unique values: x1 = x xor y y1 = x1 xor y x2 = x1 xor y1. According to our code, x2 should have y’s original value. Let’s work out the details for the last step: x2 = x1 xor y1 x2 = x1 xor (x1 xor y) // replace y1 x2 = (x1 xor x1) xor y // regroup parenthesis - order does not matter for ...
