if (node == NULL) return; FreeMem(node->left()); FreeMem(node->right()); delete node; } 3.2 在树的算法的实现中,存在很多情况下使用双游标的情况。例如在insertNode中为了找到新加入的节点的父节点,通过如下的代码实现: MyBinaryTreeNode* parent = NULL; MyBinary
在C#中,可以使用以下代码实现Binary Search Tree<T>的删除操作: 代码语言:txt 复制 public class BinarySearchTree<T> where T : IComparable<T> { private class Node { public T Value; public Node Left; public Node Right; } private Node root; // 删除节点 public void Delete(T value) { root = ...
case 1: if the delete node is leaf node, then we can simply remove it case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid binary search tree, we can copy the min value from right subtree to delete node, to convert...

Here is the pseudocode for deletion in a binary search tree: function deleteNode(root, value): if root is NULL: return root if value < root->data: root->left = deleteNode(root->left, value) else if value > root->data: root->right = deleteNode(root->right, value) else: // Case...

Binary tree (a) has 8 nodes, with node 1 as its root. Node 1's left child is node 2; node 1's right child is node 3. Notice that a node doesn't need to have both a left child and right child. In binary tree (a), node 4, for example, has only a right child. Furthermor...
