2133 - Check if Every Row and Column Contains All Numbers\. Easy An `n x n` matrix is **valid** if every row and every column contains **all** the integers from `1` to `n` ( **inclusive** ). Given an `n x n` integer matrix `matrix`, return `true` _if the matrix is **valid**._ Otherwise, return `false`. **Example 1:**  **Input:** matrix = \[\[1,2,3],[3,1,2],[2,3,1]] **Output:** true **Explanation:** In this case, n = 3, and every row and column contains the numbers 1, 2, and 3. Hence, we return true. **Example 2:**  **Input:** matrix = \[\[1,1,1],[1,2,3],[1,2,3]] **Output:** false **Explanation:** In this case, n = 3, but the first row and the first column do not contain the numbers 2 or 3. Hence, we return false. **Constraints:** * `n == matrix.length == matrix[i].length` * `1 <= n <= 100` * `1 <= matrix[i][j] <= n`
