WebDec 29, 2024 · The naive solution to this is to find all of the pairs of numbers in each array and take their AND, and then XOR all the pairs. However, this will take too long. We therefore need to take advantage of the properties of the XOR function, with a couple of key observations. The first is that in this problem, each bit is independent. WebNov 8, 2024 · Approach 2 (Using other bitwise operators): We can optimize the above solution by simulating the XOR operation without using the for loop as follows: We find all the bits where either x’s or y’s bits are set (Bitwise OR of the numbers). We need to remove those set bits where both x and y are set (~x OR ~y).
