Given a non-empty array of numbers, a0, a1, a2, - , an-1, where 0 ≤ ai < 231. Find the maximum result of ai XOR aj, where 0 ≤ i, j < n. Could you do this in O(n) runtime? Example: Input: [3, 10, 5, 25, 2, 8] Output: 28 Explanation: The maximum resul…

E. XOR Guessing 第一次做这种交互题,刚开始还看不懂,现在已经差不多可以理解了,清空缓存区用cout<<endl;即可,需要注意的是,如果用fflush(stdout)来清空缓存区,注意不能关同步 思路:最多可能是\(2^{14}-1\)总共14位数,最多可以询问两次,那么只需要分别求出其前7位和后7位即可,1~100与 x 取&,那么我们就可以得出x的前7位的值,因为1~100最多只有7位,不会影响到前7位,那么后7位只需将 x 与(1~100)<<7取…
