Machine learning algorithms can be boosted by noticing that for a hard function f, applying this operation to many copies of f results in a harder function, which is this operation's namesake lemma by Andrew Yao. The last output bit of a Toffoli gate is this operation applied to the 3rd input bit and J where J is the result of another operation on the 1st and 2nd input bits. If a drive fails, this operation can be applied to the other drives and the parity drive to recover the dead drive's contents into a hot spare in many RAID error protection schemes. Two memory addresses can be represented with one number using this operation in its namesa

If a drive fails, this operation can be applied to the other drives and the parity drive to recover the dead drive's contents into a hot spare in many RAID error protection schemes. Two memory addresses can be represented with one number using this operation in its namesake (*) linked list. Along with an AND gate, it is the other gate in a simple half-adder design. Its namesake mask can be used to toggle bits and applying this operation three times to two variables is a way of swapping them without a temporary variable. For ten points, name this logical operation that is true if exactly one of its operands is true.
