Introduction: Do I need to convert the byte order during network communication?Platforms of the same byte sequence can not perform byte sequence conversion during network communication, but must perform byte sequence conversion for cross-platform network data communication. The reason is as follows: the network protocol specifies that the first byte received is a

DS sequence tables implement output in disordered input sequence, ds There are many instances of sequence tables. When learning other programming languages, you must have learned to input a series of numbers in disorder, which requires sorting to achieve ascending or descending output. Today, we will use an ordered table to implement out-of-order Input and Output

The DS sequence table reverts input data and ds sequence data. There are two very similar processes to achieve the inverse of input data and the ordering of order tables. Therefore, the basic operations of order tables are the same: preparations before the basic operations of 0, 1 initialization of order tables, 6. insert data elements into the sequence table. To

Bessie and the cows is playing with sequences and need your help. They start with a sequence, initially containing just the number 0, and perform n operations. Each operation is one of the following:After each operation, the cows would like to know the average of the numbers in the sequence. Help them!InputThe first line contains a single integer n (1?≤?n?≤?2 105)-the number of operations. The next n lines

BNU basic problems, data structure of the basic problem, by the way.Binary tree is a kind of common data structure. We can use uppercase letters to denote the nodes of a binary tree.As follows: B / \ / \ C A DFor binary tree, there are three kinds of traversal methods, which are pre-order, middle-order and post-sequence. Now give you a binary tree of the pre-order and the middle

Problem: In the SQL Server database, it is also convenient to use the field properties of the self added column. And in Oracle, there is no such function, how to achieve it? A: Although there are no trigger in Oracle, they can be implemented by means of triggers () and sequences (sequence). Example: 1, establish the table Copy Code code as follows: CREATE TABLE User ( ID Number (6) is not NULL, Name VARCHAR2 NOT NULL primary key

PostgreSQL uses sequences to generate values for serial columns and serial columns be generally what's used for "AUTO-INCR ementing "columns in PostgreSQL. Sequences has names and is, in general, independent of any particular table so you could has one sequence generating UN Ique IDs for several different tables; The sequence name is a lastInsertId wants as its argument: For example, pdo_pgsql () r
