You are also given an integer `k`. Your task is to calculate the number of paths you can take from the top-left cell `(0, 0)` to the bottom-right cell `(m - 1, n - 1)` satisfying the following **constraints**: You can either move to the right or down. Formally, from the cell `(i, j)` you may move to the cell `(i, j + 1)` or to the cell `(i + 1, j)` if the target cell _exists_. The `XOR` of all the numbers on the path must be **equal** to `k`. Return the total number of such paths. Since the answer can be very large, return the result **modulo** `109 + 7`. **Example 1:** **Input:** grid = [[2, 1, 5], [7, 10, 0], [12, 6, 4]], k = 11 **Output:** 3 **Explanation:** The 3 paths are: `(0, 0) → (1, 0) → (2, 0) → (2, 1) → (2, 2)` `(0, 0) → (1, 0) → (1, 1) → (1, 2) → (2, 2)` `(0, 0) → (0, 1) → (1, 1) → (2, 1) → (2, 2)` **Example 2:** **Input:** grid = [[1, 3, 3, 3], [0, 3, 3, 2], [3,
