LeetCode: 236. Lowest Common Ancestor of a Binary Tree
코드가 너무 복잡하다. # Definition for a binary tree node. # class TreeNode: # def __init__(self, x): # self.val = x # self.left = None # self.right = None class Solution: def lowestCommonAncestor(self, root: 'TreeNode', p: 'TreeNode', q: 'TreeNode') -> 'TreeNode': self.ret = None self.dfs(root, p, q) return self.ret def dfs(self, node, p, q): if node == None: return None l = self.dfs(node.left, p, q) if..
