Red-black tree is a very good performance data structure, the key is that it can ensure that the worst performance is also logarithmic, mainly because it is a balanced tree, so also called the balance of the search tree. To understand the red and

In the process of using the database, if the database file is created only in internal memory, it may be deleted resulting in data loss (the SQLite file that is deleted after Root enters Data/data), in order to prevent this situation, the database

Sometimes in the project we need to use PHP to encrypt specific information, that is, through the encryption algorithm to generate an encrypted string, the encrypted string can be decrypted by the decryption algorithm, so that the program to process

Set Type 1: Overview set is a set, which is a unordered set of the string type. set is implemented through hashtable. The complexity of adding, deleting, and searching is O (1 ). for a set, we can take the Union set, intersection, and difference set.

Document directory 1) constructor and destructor 2) size, empty function judgment 3) add and delete Functions 4) traversal Function 5) operation functions Before using the set or Multiset set, you must add the header file Set and Multiset

Primary objective: to find a hash function that supports 64-bit integer computation efficiently, so that the efficiency in speed and space is higher than that of other function functions, and 32-bit integer computation in internal

Introduction to STL associated containers: the associated container is the key-Value Pair container. The key is used to store and read elements. There are four associated containers in STL: Map key-value pairs are stored in key-value pairs. Keys

What is a dictionary? A dictionary is the only type of mapping in the Python language. A hash value (key, key) and a pointer to an object (values, value) are a one-to-many relationship that is often considered a mutable hash table in the mapping

RSA Algorithm and Its Use in iOS, RSA Algorithm Used in iOS Because the project needs to transmit the user password, in order to ensure security, we need to use RSA encryption, So we learned how to use RSA encryption in iOS. On the history and

Because the project needs to transfer the user password, in order to secure the need to use RSA encryption, so learn the next RSA encryption in iOS application. About the history and principles of RSA, the following two articles are very clear: http:

1, recently developed a system, there is a need to forget the password after the mailbox back. Now the system at the time of registration will be forced to enter the mailbox, its purpose is to get back through the mail binding, can be password back.

  When looking at the Internet cafe, the movie search function (user input) exists in the page) This function cannot be made static, so it can only be dynamic. When dynamic, it will bring a great test to the database and server pressure. Therefore,

First, what is a dictionaryA dictionary is the only type of mapping in the Python language.A hash value (key, key) and a pointer to an object (values, value) are a one-to-many relationship that is often considered a mutable hash table in the mapping
