2245 - Maximum Trailing Zeros in a Cornered Path\. Medium You are given a 2D integer array `grid` of size `m x n`, where each cell contains a positive integer. A **cornered path** is defined as a set of adjacent cells with **at most** one turn. More specifically, the path should exclusively move either **horizontally** or **vertically** up to the turn (if there is one), without returning to a previously visited cell. After the turn, the path will then move exclusively in the **alternate** direction: move vertically if it moved horizontally, and vice versa, also without returning to a previously visited cell. The **product** of a path is defined as the product of all the values in the path. Return _the **maximum** number of **trailing zeros** in the product of a cornered path found in_ `grid`. Note: * **Horizontal** movement means moving in either the left or right direction. * **Vertical** movement means moving in either the up or down direction. **Example 1:**  **Input:** grid = \[\[23,17,15,3,20],[8,1,20,27,11],[9,4,6,2,21],[40,9,1,10,6],[22,7,4,5,3]] **Output:** 3 **Explanation:** The grid on the left shows a valid cornered path. It has a product of 15 \* 20 \* 6 \* 1 \* 10 = 18000 which has 3 trailing zeros. It can be shown that this is the maximum trailing zeros in the product of a cornered path. The grid in the middle is not a cornered path as it has more than one turn. The grid on the right is not a cornered path as it requires a return to a previously visited cell. **Example 2:**  **Input:** grid = \[\[4,3,2],[7,6,1],[8,8,8]] **Output:** 0 **Explanation:** The grid is shown in the figure above. There are no cornered paths in the grid that result in a product with a trailing zero. **Constraints:** * `m == grid.length` * `n == grid[i].length` * 1 <= m, n <= 105 * 1 <= m * n <= 105 * `1 <= grid[i][j] <= 1000`
