xor 1

Qaq is the most difficult question to write so many simulation questions. Good God, so I made up and checked the set .. And the query set is very god ...... Orz Type and query set... Orz To maintain the SAT, we can think like this: If the XOR values

I think the XOR thing is particularly magical, and the most amazing thing is this nature. A XOR B xor b=aSo you don't have to worry about repeating things.On the question of XOR you can go to the MO team's "Gaussian elimination of the Xor Equation

This article describes an easy-to-use encryption/decryption algorithm that uses XOR (XOR) operations. This algorithm is simple in principle and is designed to make readers have a more intuitive impression on the encryption/decryption of information.
