2373 - Largest Local Values in a Matrix\. Easy You are given an `n x n` integer matrix `grid`. Generate an integer matrix `maxLocal` of size `(n - 2) x (n - 2)` such that: * `maxLocal[i][j]` is equal to the **largest** value of the `3 x 3` matrix in `grid` centered around row `i + 1` and column `j + 1`. In other words, we want to find the largest value in every contiguous `3 x 3` matrix in `grid`. Return _the generated matrix_. **Example 1:**  **Input:** grid = \[\[9,9,8,1],[5,6,2,6],[8,2,6,4],[6,2,2,2]] **Output:** [[9,9],[8,6]] **Explanation:** The diagram above shows the original matrix and the generated matrix. Notice that each value in the generated matrix corresponds to the largest value of a contiguous 3 x 3 matrix in grid. **Example 2:**  **Input:** grid = \[\[1,1,1,1,1],[1,1,1,1,1],[1,1,2,1,1],[1,1,1,1,1],[1,1,1,1,1]] **Output:** [[2,2,2],[2,2,2],[2,2,2]] **Explanation:** Notice that the 2 is contained within every contiguous 3 x 3 matrix in grid. **Constraints:** * `n == grid.length == grid[i].length` * `3 <= n <= 100` * `1 <= grid[i][j] <= 100`
