1034 - Coloring A Border\. Medium You are given an `m x n` integer matrix `grid`, and three integers `row`, `col`, and `color`. Each value in the grid represents the color of the grid square at that location. Two squares belong to the same **connected component** if they have the same color and are next to each other in any of the 4 directions. The **border of a connected component** is all the squares in the connected component that are either **4-directionally** adjacent to a square not in the component, or on the boundary of the grid (the first or last row or column). You should color the **border** of the **connected component** that contains the square `grid[row][col]` with `color`. Return _the final grid_. **Example 1:** **Input:** grid = \[\[1,1],[1,2]], row = 0, col = 0, color = 3 **Output:** [[3,3],[3,2]] **Example 2:** **Input:** grid = \[\[1,2,2],[2,3,2]], row = 0, col = 1, color = 3 **Output:** [[1,3,3],[2,3,3]] **Example 3:** **Input:** grid = \[\[1,1,1],[1,1,1],[1,1,1]], row = 1, col = 1, color = 2 **Output:** [[2,2,2],[2,1,2],[2,2,2]] **Constraints:** * `m == grid.length` * `n == grid[i].length` * `1 <= m, n <= 50` * `1 <= grid[i][j], color <= 1000` * `0 <= row < m` * `0 <= col < n`
