public class Solution extends Object
931 - Minimum Falling Path Sum\. Medium Given an `n x n` array of integers `matrix`, return _the **minimum sum** of any **falling path** through_ `matrix`. A **falling path** starts at any element in the first row and chooses the element in the next row that is either directly below or diagonally left/right. Specifically, the next element from position `(row, col)` will be `(row + 1, col - 1)`, `(row + 1, col)`, or `(row + 1, col + 1)`. **Example 1:** ![](https://assets.leetcode.com/uploads/2021/11/03/failing1-grid.jpg) **Input:** matrix = \[\[2,1,3],[6,5,4],[7,8,9]] **Output:** 13 **Explanation:** There are two falling paths with a minimum sum as shown. **Example 2:** ![](https://assets.leetcode.com/uploads/2021/11/03/failing2-grid.jpg) **Input:** matrix = \[\[-19,57],[-40,-5]] **Output:** -59 **Explanation:** The falling path with a minimum sum is shown. **Constraints:** * `n == matrix.length == matrix[i].length` * `1 <= n <= 100` * `-100 <= matrix[i][j] <= 100`
