C Using XOR operator for finding duplicate elements in a array
7 Answers Sorted by 34 Remember these two properties of XOR operator 1 If you take xor of a number with 0 zero it would return the same number again Means n 0 n 2 If you take xor of a number with itself it would return 0 zero Means n n 0 Now Coming to the problem
