1~20 Choose 2 numbers and tell b the two numbers and the product of the 2 numbers. Then ask a know how many of these two numbers are. A said do not know, ask B to know the two number is what? B also said not to know. Then a suddenly reasoned out how many of these two numbers were, and told B he knew the answer.B then a

These will be described in a later article.B-TreeBinary search tree: 1.所有非叶子结点至多拥有两儿子（Left和Right）； 2.所有结点存储一个关键字； 3.非叶子结点的左指针指向小于其关键字的子树，右指针指向大于其关键字的子树；Such as:BTree search, starting from the root node, if the query keyword is equal to the keyword of the node, then hit;Otherwise, if the query keyword

From B tree, B + tree, and B * tree, let's talk about the R tree-structure method algorithm-blog channel-CSDN. NET From Tree B, Tree B +, and tree B *, we talk about the classificat

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 is the same as the node keyword, it hits; othe

B-Tree is a binary search tree:1. All non-leaf nodes have a maximum of two sons (left and right);2. All nodes store a keyword;3.

There are two arrays A and B, all of which are N in size. The values of the array elements are unordered due to arbitrary integer numbers;Requirement: by exchanging elements in A and B, the difference between the sum of Elements A and B is minimized. The sum of the current array A and array B isA = sum (a)-sum (

lead to different structures:The right side is also a binary tree, but its search performance is already linear; the same keyword set can lead to differenttree structure index; therefore, the use of a two-fork tree should also consider as far as possible to keep the structure of the left of the two tree, and avoid the structure of the right graph, it isis the so-called "balance" problem;The actual use of the two-fork tree is based on the original binary tree with the balance algorithm, namely "

Database B tree B + tree, database B tree In database indexes, B or B + trees are generally used for retrieval and query. The following describes how to query data in two data structures: 1) B tree

The Python manual has an example for outputting a Fibonacci sequence within 10. The code is as follows:1 A, b = 0, 12 while B :3 print(b)4 C10/>a, B = B, a+bSome Python features are used.After the study explainedThe first line, a, B
