- * 931. Minimum Falling Path Sum
- *
- * Given a square array of integers A, we want the minimum sum of a falling path through A.
- * A falling path starts at any element in the first row, and chooses one element from each row.
- * The next row's choice must be in a column that is different from the previous row's column by at most one.
- *
- * Example 1:
- * Input: [[1,2,3],[4,5,6],[7,8,9]]
- * Output: 12
- * Explanation:
- * The possible falling paths are:
- * [1,4,7], [1,4,8], [1,5,7], [1,5,8], [1,5,9]
- * [2,4,7], [2,4,8], [2,5,7], [2,5,8], [2,5,9], [2,6,8], [2,6,9]
- * [3,5,7], [3,5,8], [3,5,9], [3,6,8], [3,6,9]
- * The falling path with the smallest sum is [1,4,7], so the answer is 12.
- *
- * Note:
- * 1 <= A.length == A[0].length <= 100
- * -100 <= A[i][j] <= 100
- * */
