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 result is ...
LeetCode421. Maximum XOR of Two Numbers in an Array 这道题的题目很好理解,就是给你一个非空数组,求出数组中任意两个数异或后能得到的最大值。原题链接:LeetCode421。根据题目下面的tag的提示,本题的解题思路是Trie树的利用和整数的位操作。 这里Trie树建立的思路是,整数在存储时是一个占据32bit的数,因...

Suppose we 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 ...

Take sum of the set and find the greatest total sum of current and some sum in the array. As any sum of two numbers less than m can go no greater than 2m, we can consider just two values: the greatest number in array and the greatest number less thanm - currentSum in the ar...
Kadane’s algorithm is an efficient algorithm used to find the maximum sum subarray within a given array of integers. It was proposed by computer scientist Jay Kadane in 1984. The algorithm works by maintaining two variables: "max_so_far" and "max_ending_here". "max_so_far" keeps track ...
