1289 - Minimum Falling Path Sum II\. Hard Given an `n x n` integer matrix `grid`, return _the minimum sum of a **falling path with non-zero shifts**_. A **falling path with non-zero shifts** is a choice of exactly one element from each row of `grid` such that no two elements chosen in adjacent rows are in the same column. **Example 1:** ![](https://assets.leetcode.com/uploads/2021/08/10/falling-grid.jpg) **Input:** arr = \[\[1,2,3],[4,5,6],[7,8,9]] **Output:** 13 **Explanation:** The possible falling paths are: [1,5,9], [1,5,7], [1,6,7], [1,6,8], [2,4,8], [2,4,9], [2,6,7], [2,6,8], [3,4,8], [3,4,9], [3,5,7], [3,5,9] The falling path with the smallest sum is [1,5,7], so the answer is 13. **Example 2:** **Input:** grid = \[\[7]] **Output:** 7 **Constraints:** * `n == grid.length == grid[i].length` * `1 <= n <= 200` * `-99 <= grid[i][j] <= 99`
