• New algorithm
• Update to an existing algorithm
• Error
• Proposal to the Repository

Details:
The XOR swap algorithm allows two variables to be swapped without using a temporary variable. This is achieved through a series of XOR operations, which manipulate the bits of the numbers involved. The algorithm can be beneficial in scenarios where memory usage is a concern, though it is more of a conceptual approach than a practical one in modern programming due to readability concerns.

The implementation will include:

1. A function **xorSwap(a, b)** that takes two integers and swaps them using XOR.
2. Example usage to illustrate how the function works.
3. Potential performance considerations compared to traditional swap methods.

This addition will enhance the repository by providing an interesting algorithmic technique that demonstrates the power of bitwise operations.
