题目: Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. For example, given the following triangle [ [2], [3,4], [6,5,7], [4,1,8,3] ] The minimum path sum from top to bottom is11…

前言 时隔这么久才发了这篇早在三周前就应该发出来的课堂笔记,由于懒癌犯了,加上各种原因,实在是应该反思.好多课堂上老师说的重要的东西可能细节上有一些急记不住了,但是幸好做了一些笔记,还能够让自己回想起来.动态规划算是我的一道大坎了,本科的时候就基本没有学过,研一的时候老师上课也是吃力的跟上了老师的步伐,其实那个时候老师总结的还是挺好的:把动态规划的题目都分成了一维动规.二维遍历.二维不遍历等一系列的问题.这次听了老师的课程,觉得还是需要更加集中的去把各种题进行一个分类吧,然后有针对的去准备,虽然…
