"Web15 Jan 2014 · There's a relationship between a + b and a ^ b. It is given by: a + b = a^b + 2* (a & b) Hence, a^b = a + b - 2* (a & b) (where ^ is the bitwise XOR and & is bitwise AND) see this link to get some more idea about the above relation. Hence, for every a and b, where a & b = 0 you will get a+b = a^b which explains the sum part. " - Sum of xor of pairs smart interviews
