[LeetCode] N-ary Tree Level Order Traversal N叉樹層序遍歷
Given an n-ary tree, return the level order traversal of its nodes‘ values. (ie, from left to right, level by level).
For example, given a 3-ary tree:
We should return its level order traversal:
[
[1],
[3,2,4],
[5,6]
]
Note:
- The depth of the tree is at most
1000. - The total number of nodes is at most
5000.
