给定一个方形整数数组 A,我们想要得到通过 A 的下降路径的最小和. 下降路径可以从第一行中的任何元素开始,并从每一行中选择一个元素.在下一行选择的元素和当前行所选元素最多相隔一列. 示例: 输入:[[1,2,3],[4,5,6],[7,8,9]] 输出:12 解释: 可能的下降路径有: [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]…

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 t…

Leetcode 931. Minimum falling path sum 最小下降路径和(动态规划) 题目描述 已知一个正方形二维数组A,我们想找到一条最小下降路径的和 所谓下降路径是指,从一行到下一行,只能选择间距不超过1的列(也就是说第一行的第一列,只能选择第二行的第一列和第二列:第二行的第二列,只能选择第三行的第一列第二列第三列),最小下降路径就是这个路径的和最小 测试样例 Input: [[1,2,3],[4,5,6],[7,8,9]] Output: 12 Explanation:…
