I'm not sure what the author has against america flooring conventions, but it took me longer to figure out what the actual problem was than it took to solve.

you have the two backwards, user2791371

I mean, yeah that certainly is one way to do it.

my code looked something similar to this, but I couldn't get "numbers == null" to identify a null array. I had to use: "numbers?.Any() != true"

but why

jesus dude

wasn't sure that it was possible to shit post code until now

what no java?

I wish I could find external material to explain what's going on, but I'm struggling to find anything concrete. The operator is called a bit shift operator.

According to Progamiz: "These operators are not generally used in Java" (referring to bitwise and bit shift operators)

What I do know: in this case the operator "^=" will cancel out similar numbers, then will set the sum to the unique number like any other assignment operator.

I had a similar solution. To make this a little easier on the eyes I would recommend using parenthesis.
