Learn how to find the maximum XOR of two numbers in an array using C++. This article provides detailed explanations and examples.
C = xor(A,B)performs a logical exclusive-OR of arraysAandBand returns an array containing elements set to either logical 1 (true) or logical 0 (false). An element of the output array is set to logical 1 (true) ifAorB, but not both, contains a nonzero element at that same array ...
所以这里如果要找 XOR 最大的结果,最好能找到两个数字,他们的二进制表达最好在每一位上都不同。而且 XOR 是具有交换律的,如果你有 a ^ b = c,你同时可以得到 a ^ c = b 和 b ^ c = a。假如 a 和 b 是来自于 nums 的数字的话,我们为了要使 c 最大,我们可以试图去找一个前缀很大的数字 a ...

Suppose we have an array A[] with n positive elements. We have to create another array B, such that B[i] is XOR of all elements of A[] except A[i]. So if the A = [2, 1, 5, 9], then B = [13, 14, 10, 6] To solve this, at first we have to find...

421. Maximum XOR of Two Numbers in an Array 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?
You are given an array of integers aa of size nn. This array is non-decreasing, i. e. a1≤a2≤⋯≤ana1≤a2≤⋯≤an. You have to find arrays of integers bb of size 2n−12n−1, such that: b2i−1=aib2i−1=ai (1≤i≤n1≤i≤n); array bb is non-decreasing; b1...
