Reversible actions with XOR: It's convenient to occasionally be able to reverse a value's bits so that they can be quickly converted back to the original value. Bit restoration and inversion demonstrate a construction programme to carry it out. This can be used, for example, to exchange two numbers without requiring interim storage.
