二刷吧。。不知道为什么houserobbery系列我找不到笔记，不过印象中做了好几次了。不是很难，用的post-order做bottom-up的运算。对于一个Node来说，有2种情况，一种是选（自己+下下层）；一种是选左右children.其实就是选自己和不选自己的区别。其实更像是dfs的题而不是DP的题。Time:O(n)Space:O(lgn)publicclassSolution{publi

House Robber III

题目：对于一个二叉树，不能同时取某个分支上两端的两个节点，求能取得的最大的值。（这是题目大意）思路：对于一个二叉树，如果根据条件判断该二叉树根节点可以取，则传入参数true，如果某个二叉树的根节点不可以取，则传入false，当参数为true时，到底真正取与不去分两种情况，类似于0-1背包问题，然后返回那个结果比较大的情况。当参数为false，则根节点一定是不能取了，则返回（root.left，tr

House Robber III （C++实现）

解题思路：递归求解，若为空树返回0；若只有一个根结点就返回根结点的值；否则，若根结点有孩子，两种抢法：抢根结点！不抢根结点，抢根结点的孩子子树！取最大值（选抢的多的方案）！（注：抢根结点，就不能抢根结点的孩子！但可以抢根结点的孩子的孩子~~~）C++代码：/** *Definitionforabinarytreenode. *structTreeNode{ *intval; *TreeNode*l

House Robber III+198. House Robber

HouseRobberIII对二叉树的各种操作还不太熟....一开始是自己写的程序，然而逻辑有些问题，居然认为必须隔层访问（其实隔两层/三层也是可以的...所以重点是当前访问的结点是否被计入）。参考了他人的代码，解题思路如下：针对正在访问的结点，两种情况取较大值，（1）当前结点值计入，则结果是左孩子和右孩子不计入时两个子树的count；（2）当前结点值不计入，则结果是左子树两种情况（计入/不计入）
