In Java XOR with three true inputs returns true. Why?

Question

The following code

System.out.println(\"1 0 0: \" + (true ^ false ^ false));
System.out.println(\"1 0 1: \" + (true ^ false ^ true));
System.out.println(\"1 1 0:         


        

Answer 1

true ^ true ^ true can be written (for understanding) as ( true ^ true ) ^ true which is true.

If A, B, C are inputs, for the logic that you are looking for, you need something like this

(A & !B & !C) | (!A & B & !C) | (!A & !B & C)
