429 - N-ary Tree Level Order Traversal\. Medium Given an n-ary tree, return the _level order_ traversal of its nodes' values. _Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value (See examples)._ **Example 1:**  **Input:** root = [1,null,3,2,4,null,5,6] **Output:** [[1],[3,2,4],[5,6]] **Example 2:**  **Input:** root = [1,null,2,3,4,5,null,null,6,7,null,8,null,9,10,null,null,11,null,12,null,13,null,null,14] **Output:** [[1],[2,3,4,5],[6,7,8,9,10],[11,12,13],[14]] **Constraints:** * The height of the n-ary tree is less than or equal to `1000` * The total number of nodes is between [0, 104]
