You might, for instance, want to add all the values in the tree or find the largest one. For all these operations, you will need to visit each node of the tree. Linear data structures like arrays, stacks, queues, and linked list have only one way to read the data. But a ...
discussed the In-order tree traversal algorithm in Python. In next articles, we will implement other tree traversal algorithms such as preorder tree traversal, and postorder tree traversal algorithm. To learn more about other data structures, you can read this article onLinked List in Python....

The total number of nodes is at most 5000. 题目大意 N叉树的层次遍历。 解题方法 方法一:BFS 首先得明白,这个N叉树是什么样的数据结构定义的。val是节点的值,children是一个列表,这个列表保存了其所有节点。 层次遍历比较好理解,就是每层的值保存在一个list中,总的再返回一个list即可。
