Just got a simple question from a friend; still thinking. Let's share it!
Is it possible to get a, b, c when you have a⊕b, b⊕c, a⊕c ?
where ⊕ is the boolean XOR (exclusive OR) operator.
a,b,c are any boolean numbers with the same length.
For the sake of simplicity, consider a,b,c as bytes (length is 8 bits).
Edit: You can use other operators too.
Edit 2: Though it's preferable to use only ⊕ (if possible) (removed, use any operator)
Note 1: Answer without explanations (e.g. yes
/no
) are not allowed.
Note 2: This is a puzzling programming, math-related question and could be placed on Puzzling.SE, Programming.SE, StackOverflow and Math.SE. So excuse me or migrate the question if I pasted it on the wrong SE forum.
