Xor Swap.... https://en.wikipedia.org/wiki/XOR_swap_algorithm https://en.wikipedia.org/wiki/XOR_swap_algorithm not because it's super practical ( and there are other variations using other operators ) I like it because it is super simple and when I first encountered it early on in my learning, it was really not immediately obvious why it worked. It's probably been the simplest piece of code that's surprised me.
