1878 - Get Biggest Three Rhombus Sums in a Grid\. Medium You are given an `m x n` integer matrix `grid`. A **rhombus sum** is the sum of the elements that form **the** **border** of a regular rhombus shape in `grid`. The rhombus must have the shape of a square rotated 45 degrees with each of the corners centered in a grid cell. Below is an image of four valid rhombus shapes with the corresponding colored cells that should be included in each **rhombus sum**:  Note that the rhombus can have an area of 0, which is depicted by the purple rhombus in the bottom right corner. Return _the biggest three **distinct rhombus sums** in the_ `grid` _in **descending order**__. If there are less than three distinct values, return all of them_. **Example 1:**  **Input:** grid = \[\[3,4,5,1,3],[3,3,4,2,3],[20,30,200,40,10],[1,5,5,4,1],[4,3,2,2,5]] **Output:** [228,216,211] **Explanation:** The rhombus shapes for the three biggest distinct rhombus sums are depicted above. - Blue: 20 + 3 + 200 + 5 = 228 - Red: 200 + 2 + 10 + 4 = 216 - Green: 5 + 200 + 4 + 2 = 211 **Example 2:**  **Input:** grid = \[\[1,2,3],[4,5,6],[7,8,9]] **Output:** [20,9,8] **Explanation:** The rhombus shapes for the three biggest distinct rhombus sums are depicted above. - Blue: 4 + 2 + 6 + 8 = 20 - Red: 9 (area 0 rhombus in the bottom right corner) - Green: 8 (area 0 rhombus in the bottom middle) **Example 3:** **Input:** grid = \[\[7,7,7]] **Output:** [7] **Explanation:** All three possible rhombus sums are the same, so return [7]. **Constraints:** * `m == grid.length` * `n == grid[i].length` * `1 <= m, n <= 50` * 1 <= grid[i][j] <= 105
