Solution

The correct answer is Bitwise XOR. This operation is commonly used to exchange the values of two variables without using a temporary variable. Here's how it works:

Let's say we have two variables, a and b. We want to swap their values.

  1. a = a XOR b
  2. b = a XOR b
  3. a = a XOR b

After these operations, the values of a and b will be swapped. This is because the XOR operation is both commutative and associative, meaning the order in which the operations are performed does not change the result.
