Web2 hours ago · NOTE 1: XOR of X and Y is defined as X ^ Y where '^' is the BITWISE XOR operator. NOTE 2: Your code will be run against a maximum of 100000 Test Cases. My approach Since a+b = a^b if a&b==0 . So acc to this I had written my code but test cases are not passing. WebOct 25, 2013 · 4 Answers. Sorted by: 16. The &= and the ++ together are the same as X = (X + 1) % 1024; but can be computed faster by the CPU. 1024-1 is 11 1111 1111 in binary, so for numbers where X < 1024, a bitwise AND will have no effect (since any bit & 1 = the same bit). Interesting things only start to happen where X ≥ 1024, so let's consider the ...
