https://leetcode.com/problems/maximum-xor-of-two-numbers-in-an-array/description/ 解题方法: 在解题之前,首先要了解2个事情: 两个数XOR的结果取决于这两位数的二进制形式每一位是否相同。当相同时,结果在这一位上为0;当不同时,结果在这一位上为1。 假设我们有3个数:a, b, c;当a 和 b以及b和c...
leetcode 421. Maximum XOR of Two Numbers in an Array 最大的异或运算值 + 位运算 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:...

have a non-empty array of numbers, a0, a1, a2, … , an-1, where 0 ≤ ai < 231. We have to find the maximum result of ai XOR aj, where 0 ≤ i, j < n. So if the input is like [3,10,5,15,2,8], then the output will be 28. The max result will be 5 XOR 25 = ...
Given an integer array nums, return the maximum result of nums[i] XOR nums[j], where 0 <= i <= j < n. Example 1: Input: nums = [3,10,5,25,2,8] Output: 28 Explanation: The maximum result is 5 XOR 25 = 28. Example 2: ...
