Īn Java (and many other programming languages), ^ denotes the boolean "exclusive or" or "xor" function. A xor B is equivalent to (A or B) and not (A and B), or in English "one or the other but not both".

0 ^ 0 == 0
0 ^ 1 == 1
1 ^ 0 == 1
1 ^ 1 == 0

I am wondering - what does '^' do in the second if statement? Does it work the same way like '&&'?

How can I get the arrays that are used to verify your attempt? I keep failing a test, because it expects 1, while my program outputs -1.
