Question for a normal two-fork tree, how to find the distance between two given nodes? Distance refers to the number of bars that are required to connect the minimum edges of two nodes. For example, the following two-fork tree: The problem is a comprehensive review of the two-tree related knowledge, we recommend that we first try to solve the analysis: assuming that the given node is Node1,node2, can be div
Given A linked list, reverse the nodes of a linked list K at a time and return its modified list. If the number of nodes is not a multiple of K then left-out nodes in the end should remain as it is. You may not alter the values in the nodes, and only nodes itself is changed.

SQL parent node to find all child nodes, SQL parent node
How can we save data in a tree structure? Commonly Used in SQL is the parent node method. Create a table as follows:
CREATE TABLE category ( id LONG, parentId LONG, name String(20) )INSERT INTO category VALUES ( 1, NULL, 'Root' )INSERT INTO category VALUES ( 2, 1, 'Branch1' )INSERT INTO category VALUES ( 3, 1, 'Branch2' )INSERT INTO category VALUES ( 4, 3, 'SubBranch1' )INSERT INTO category VALU

May I ask the great gods how to tell if the two XML nodes are the same when the XML node hierarchy is uncertain?
Here we agree that when a node has child nodes, the order of the child nodes does not affect the decision of the XML node.
For example, you have the following two XML nodes:
