124 Binary Tree Maximum Path Sum
题目： 124 Binary Tree Maximum Path Sum
这道题就是分别算出左子树和右子树的可能最大和，然后对Path的值进行更新即可
class Solution:def __init__(self):self.ans = -100000def maxPathSum(self, root):self.getSum(root)return self.ansdef getSum(self, root):if not root:return 0left = max(0, self.getSum(root.left))right = max(0, self.getSum(root.right))self.ans = max(self.ans, left + root.val + right)return root.val + max(left,right)
