LeetCode（124） Binary Tree Maximum Path Sum
Given a binary tree, find the maximum path sum.
For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path does not need to go through the root.
For example:
Given the below binary tree,
1
/ \
2 3
Return 6.

解題思路： 回溯 對於樹的一個結點來說，[左子樹值]、[右子樹值]、[左子樹+右子樹+當前結點值]，這三種組合中，必然有一個最大值，將這個最大值儲存在maxValue[0]中，實時更新即可。 函式maxValue返回的是如果一定要包含當前結點值時的最大數值。 提交程式碼： cl

又是一道好題啊。難點在於如何根據題意設計DFS過程。想一想如何求得由這個節點向下的路徑最大值。這個節點的值必然包括，左邊的值是max(0,l),右邊的是max(0,r)。所以設定helper函式是求包括這個節點在內的最大單邊路徑和，不能直接設定為最大雙邊路徑和（這樣會分岔不符合題意）。
