30.8 Structure and representation of MIB Object Names We said that ASN.1 specifies what to represent both data items and names. However, understanding the names used for Mibvariables requires us to know about the underlying namespace. Names used for MIB variables is taken from the object identifier namespace administered by ISO and ITU. the key idea behind the o
The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article and later in this article ensures that the LGN efficiency can be achieved in the worst case, and we need to make sure
Written in the front: according to the focus of the Han Hao painting, at this stage, the tree, map to understand the logical structure, storage mode, not required code implementation. 6th Chapter Two fork trees and trees 6.1 Two fork tree: concept and nature 6.1.1 Concept and Nature Definitions and diagrams several basic concepts

problem Description
Given two trees T1 and T2. If T1 can be converted to T2 by several times or so, we call the two trees "isomorphic". For example, the two trees given in Figure 1 are isomorphic because we swap the children of the nodes A, B, and g of one of the trees to get another

order of the data in the clustered index is consistent with the index order, that is, as long as the index is adjacent, the corresponding data must also be stored on the disk adjacent to it. If the primary key is not an ID, imagine what it will do, constantly adjust the physical address of the data, paging, and of course there are other measures to reduce these operations, but it can not be completely avoided. However, if it is a self-added, it is simple, it only needs a page to write, the inde
the nodes are properly renamed, the two trees can be completely equal (the node corresponds to the same, the nodal relationship is equal), called the Two trees isomorphic.

B tree
That is, the binary search tree:
1. All non-leaf nodes have at most two sons (Left and Right );
2. All nodes store a keyword;
3. The left pointer of a non-leaf node points to the subtree smaller than its keyword, And the right Pointer Points to the subtree larger than its keyword;
For example:
B-tree search starts from the root node. If the query keyword i
