Given an m x n integers matrix, return the length of the longest increasing path in matrix. From each cell, you can either move in four directions: left, right, up, or down. You may not move diagonally or move outside the boundary (i.e., wrap-around is not allowed). Example 1: ...

LeetCode 329. Longest Increasing Path in a Matrix 简介:给定一个整数矩阵,找出最长递增路径的长度。对于每个单元格,你可以往上,下,左,右四个方向移动。 你不能在对角线方向上移动或移动到边界外(即不允许环绕)。 Description Given an integer matrix, find the length of the longest increasing path....
329. Longest Increasing Path in a Matrix 这个题是在二维数组中找递增序列的最长长度。 因为使用dfs都是从当前位置进行搜索,所以每次dp计算的值是以当前为起点的最长长度。 这里使用了一个二维数组记录每个位置最长长度,在dfs递归的时候,同时也起到了之前visited数组的作用,只要这个位置的dp值不为0,就表示已经访问...
