Bitwise xor subsequence
WebFor example, adding vectors → OP and → OQ we get → OR where R(1, 0) turns out to be the point corresponding the xor of 2 and 3. This is all there is to it. Transforming xor operations to bitwise addition modulo 2 and, in some cases, vector addition in this way can be helpful in some problems. WebMar 17, 2024 · The subset is (4, 5) whose bitwise AND is 4 and the bitwise XOR is 1. Another such subset is (4, 6), whose bitwise AND is 4 and the bitwise XOR is 2. Since the maximum size is still 2, the answer is 2. Approach. Our approach is to find the bitwise AND and the bitwise XOR for all possible subsets and update the answer whenever we find a …
