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...

上述代码中,我们定义了一个二叉搜索树节点结构体Node,每个节点包含一个整型数据data,以及左子树和右子树的指针。我们实现了以下几个函数: 函数中,我们创建了一个空的二叉搜索树root,并插入一些节点。最后,我们进行中序遍历,并打印结果。 请注意,这只是一个相对复杂的示例代码,演示了如何实现一个简单的二叉搜索树。

二叉树的堂兄弟 Cousins in Binary Tree 在二叉树中,根节点位于深度0处,每个深度为k的节点的子节点位于深度k+1处。 如果二叉树的两个节点深度相同,但 父节点不同 ,则它们是一对堂兄弟节点。 我们给出了具有唯一值的二叉树的根节点 root ,以及树中两个不同节点的值 x 和 y 。
binary trees store data in a non-linear fashion. After discussing the properties of binary trees, we'll look at a more specific type of binary tree—the binary search tree, or BST. A BST imposes certain rules on how the items of the tree are arranged. These rules provide BSTs with a ...
It took me some time to figure out how to borrow or move the data in the method. Once I got it, it made so much sense! Let's write some tests for it🧑🔬 #[test] fn insert() { let mut tree = BinaryTree::new(1); tree.insert(2); tree.insert(3); tree.insert(4); ...
