If we know the sum and XOR of two numbers, then can we find out what are the two numbers?
I am trying to resolve a problem and the above problem is a part of that. Although, I do have another solution for that problem but I still want a solution for this.
No.
Example: SUM=7, XOR=7
Possible answers:
a) 1, 6
b) 2, 5
c) 3, 4
Not enough information to decide which pair (a, b or c) is the original pair of numbers.
