Recently you are planning to use python as a test case for functional testing and stress testing of game servers;Because the server is written in C + +, the TCP protocol, the current architecture is intended to use the python constructs the structure, transmits to the C + + layer to send the socket to the game server, the response message is then referred to Python for verification;Begin:The first is the C + + call Python layer needs to get through;

Concept: A list is a linear collection of things that are organized in a linear way.
Features: The capacity of the list collection can grow as needed; The list collection can add or remove elements at the middle and end of the list.
Categories: Lists have three types of ord

The function of the organization's architecture module is to display a tree-type corporate organization schema that can be added to each layer at the last level. You can also delete any department, and if you delete the Department of the Ribbon department, it is deleted together with its subordinate departments.

Qifang is determined to change the old cainiao image. He also thought about prawn addiction. He recently joined the game again and studied "design patterns" and "data structures" behind closed doors. He also hoped to take care of the old birds! Let old dishes become old birds as soon as possible! * ^_^ *
The usage of one-dimensional arrays is also found. You can refer to the following questions:
Textbook: data structure, in C language, published
Linked lists are one of the simplest data structures, and when we use arrays to store data, frequent insertions and deletions can consume a lot of performance, and a linked list is a linear data structure that is suitable for frequently inserting and deleting operations.A detailed introduction to the linked list can be seen here, in layman's terms, the list is made up of a number of nodes, each node has a pointer, this pointer holds the position of th
, delete the node and set the parent's child reference to null. The color of brothers is the most important thing to delete.
Problems and Solutions in teaching material Learning
Problem 1: In the deletion of the red/black tree, an iteration termination condition is (current. Color = red), which cannot be understood.
Problem 1: because the number of black nodes in each path is the same, when the c

This class provides a set of abstract methods that can be used to construct a cluster. The collectionbase class also provides a basic data structure-innerlist (an arraylist ). This s
