如何获得连通分量的最大值和坐标？

def dfs(matrix, visited, row, col):
    if row < 0 or row >= len(matrix) or col < 0 or col >= len(matrix[0]) or visited[row][col] or matrix[row][col] == 0:
        return 0
    
    visited[row][col] = True
    count = 1
    
    count += dfs(matrix, visited, row-1, col)  # 上
    count += dfs(matrix, visited, row+1, col)  # 下
    count += dfs(matrix, visited, row, col-1)  # 左
    count += dfs(matrix, visited, row, col+1)  # 右
    
    return count

def get_max_connected_component(matrix):
    max_count = 0
    max_coord = (0, 0)
    visited = [[False for _ in range(len(matrix[0]))] for _ in range(len(matrix))]
    
    for i in range(len(matrix)):
        for j in range(len(matrix[0])):
            if not visited[i][j] and matrix[i][j] == 1:
                count = dfs(matrix, visited, i, j)
                if count > max_count:
                    max_count = count
                    max_coord = (i, j)
    
    return max_count, max_coord
