+ * 1219. Path with Maximum Gold
+ * In a gold mine grid of size m x n, each cell in this mine has an integer representing the amount of gold in that cell, 0 if it is empty.
+ *
+ * Return the maximum amount of gold you can collect under the conditions:
+ * - Every time you are located in a cell you will collect all the gold in that cell.
+ * - From your position, you can walk one step to the left, right, up, or down.
+ * - You can't visit the same cell more than once.
+ * - Never visit a cell with 0 gold.
+ * - You can start and stop collecting gold from any position in the grid that has some gold.
