[Leetcode/파이썬] 104. Maximum Depth of Binary Tree
Maximum Depth of Binary TreeGiven the root of a binary tree, return its maximum depth.A binary tree's maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Example 1:Input: root = [3,9,20,null,null,15,7]Output: 3Example 2:Input: root = [1,null,2]Output: 2 Constraints:The number of nodes in the tree is in the range [0, 104].-100 # Definiti..
