Can you solve this real interview question? Longest Increasing Path in a Matrix - 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 dow
Can you solve this real interview question? Longest ZigZag Path in a Binary Tree - You are given the root of a binary tree. A ZigZag path for a binary tree is defined as follow: * Choose any node in the binary tree and a direction (right or left). *
Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). Example 1: Input: nums = [ [...

我的想法:类似Largest Divisible Subset, 除了一个dp[i][j]记录longest length以外,另外再用一个matrix pre[i][j]记录(i,j)longest increasing path上一跳位置, 并用一个variable记录最后最长的path的起始位置(第19行每次res更新时更新)。最后通过这个起始位置沿着一个一个上一跳位置,可以求出path ...
