# 1707. Maximum XOR With an Element From Array

https://leetcode.com/problems/maximum-xor-with-an-element-from-array

## Description

You are given an array `nums` consisting of non-negative integers. You are also given a `queries` array, where `queries[i] = [xi, mi]`.

The answer to the `ith` query is the maximum bitwise `XOR` value of `xi` and any element of `nums` that does not exceed `mi`. In other words, the answer is `max(nums[j] XOR xi)` for all `j` such that `nums[j] <= mi`. If all elements in `nums` are larger than `mi`, then the answer is `-1`.

Return _an integer array_ `answer` _where_ `answer.length == queries.length` _and_ `answer[i]` _is the answer to the_ `ith` _query._

**Example 1:**

```
**Input:** nums = [0,1,2,3,4], queries = [[3,1],[1,3],[5,6]]
**Output:** [3,3,7]
**Explanation:**
1) 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.
2) 1 XOR 2 = 3.
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:**

* `1 <= nums.length, queries.length <= 105`
* `queries[i].length == 2`
* `0 <= nums[j], xi, mi <= 109`
