public final class Solution1707 - Maximum XOR With an Element From Array.
Hard
You are given an array
numsconsisting of non-negative integers. You are also given aqueriesarray, where <code>queriesi = x<sub>i</sub>, m<sub>i</sub></code>.The answer to the <code>i<sup>th</sup></code> query is the maximum bitwise
XORvalue of <code>x<sub>i</sub></code> and any element ofnumsthat does not exceed <code>m<sub>i</sub></code>. In other words, the answer is <code>max(numsj XOR x<sub>i</sub>)</code> for alljsuch that <code>numsj<= m<sub>i</sub></code>. If all elements innumsare larger than <code>m<sub>i</sub></code>, then the answer is-1.Return an integer array
answerwhereanswer.length == queries.lengthandanswer[i]is the answer to the <code>i<sup>th</sup></code> query.Example 1:
Input: nums = 0,1,2,3,4, queries = [3,1,1,3,5,6]
Output: 3,3,7
Explanation:
0 and 1 are the only two integers not greater than 1. 0 XOR 3 = 3 and 1 XOR 3 = 2. The larger of the two is 3.
1 XOR 2 = 3.
5 XOR 2 = 7.
Example 2:
Input: nums = 5,2,4,6,6,3, queries = [12,4,8,1,6,3]
Output: 15,-1,5
Constraints:
<code>1 <= nums.length, queries.length <= 10<sup>5</sup></code>
queries[i].length == 2<code>0 <= numsj, x<sub>i</sub>, m<sub>i</sub><= 10<sup>9</sup></code>
