bst.root = bst.deleteNode(bst.root, 30) # 打印删除节点后的BST print("\nInorder traversal of the modified tree") bst.inorder(bst.root) 在这个示例中,我们首先创建了一个BST,并打印了它的中序遍历结果。然后,我们调用deleteNode方法来删除值为30的节点,并再次打印BST的中序遍历结果以确认删除操作是否...
The key to this problem is to devise an algorithm for embedding a full binary tree in the faulty hypercube. Supposing that the root of the tree must be mapped to a specified hypercube node, we show how to embed an (n–1)-tree (a full binary tree with 2 n–1-1 nodes) into an n...

Given a binary tree, write an iterative algorithm to print the leaf-to-root path for every leaf node. Use of recursion is prohibited. For example, consider the following binary tree: There are five leaf-to-root paths in the above binary tree: ...
二分搜索树(Binary Search Tree,简称BST)是一种特殊的树形数据结构,它的左子树上所有节点的值都小于根节点的值,而右子树上所有节点的值都大于根节点的值。二分搜索树在数据查找、插入和删除操作中有着广泛的应用。深度优先遍历(Depth-First Search,简称DFS)是一种用于遍历或搜索树或图的算法。在二分搜索树中,深...
