1738 - Find Kth Largest XOR Coordinate Value\.
Medium
You are given a 2D `matrix` of size `m x n`, consisting of non-negative integers. You are also given an integer `k`.
The **value** of coordinate `(a, b)` of the matrix is the XOR of all `matrix[i][j]` where `0 <= i <= a < m` and `0 <= j <= b < n` **(0-indexed)**.
Find the kth largest value **(1-indexed)** of all the coordinates of `matrix`.
**Example 1:**
**Input:** matrix = \[\[5,2],[1,6]], k = 1
**Output:** 7
**Explanation:** The value of coordinate (0,1) is 5 XOR 2 = 7, which is the largest value.
**Example 2:**
**Input:** matrix = \[\[5,2],[1,6]], k = 2
**Output:** 5
**Explanation:** The value of coordinate (0,0) is 5 = 5, which is the 2nd largest value.
**Example 3:**
**Input:** matrix = \[\[5,2],[1,6]], k = 3
**Output:** 4
**Explanation:** The value of coordinate (1,0) is 5 XOR 1 = 4, which is the 3rd largest value.
**Constraints:**
* `m == matrix.length`
* `n == matrix[i].length`
* `1 <= m, n <= 1000`
* 0 <= matrix[i][j] <= 106
* `1 <= k <= m * n`
