First of all, we need to learn two structures: (1) Binary Tree (2) Deque abinary treeis atree data structurein which each node has at most twochildren, which are referred to as theleft childand theright child. adouble-ended queue(abbreviated todequeis anabstract data typethat generalizes...

"The intuitive concept of a tree implies that we organize the data." 树是一种非线性的数据结构,它是由 n(n >= 0)个有限节点组成的一个具有层次关系的集合。 ❓ 那么为什么叫 "树" 呢? 💡 我们之所以把它成为 "树",是因为它很像我们现实生活中的树。只是它是倒过来的,根朝上叶子朝下。 0x01...

297. Serialize and Deserialize Binary Tree Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another comput...
The base Node class represents a node in a general tree, one whose nodes can have an arbitrary number of children. To model this, we'll create not just a Node class, but a NodeList class as well. The Node class contains some data and a NodeList instance, which represents the node's ...
