【LeetCode】64. Minimum Path Sum 解题报告(Python) 题目分析: 这一题与【LeetCode】62. Unique Paths,【LeetCode】63. Unique Paths II相似度很高,这次是每次走的路径长度给定了,求的是最短路径,可以建立二维dp数组解决,属于较简单的动态规划。其实题目也就是让求有向图的最短路径问题。 解题思路: 我们创建...
Minimum Path Sum -- LeetCode 原题链接:http://oj.leetcode.com/problems/minimum-path-sum/ 这道题跟Unique Paths,Unique Paths II是相同类型的。事实上,这道题是上面两道题的general版本,是寻找带权重的path。在Unique Paths中,我们假设每个格子权重都是1,而在Unique Paths II中我们假设障碍格子的权重是...
