<1>, C++ implements multi-thread synchronization processing: controlling the output sequence of ABC, outputting 10 groups, mutex+condition_variable

Table of Contents need: analyze: Some code implementation: 1. Operations implemented using only flag bits: 2. For greater security, the mutex lock code is added: 3. Use it with unique_lock to make the code safer Four: Use guard lock lock_guard to work with it 5. You can also use condition variables to process, which will […]

[Data structure] Sequence table | Detailed explanation

There are two basic storage structures used to store linear tables in computers: sequential storage structures and chained storage structures. This article introduces the use of sequential storage structure to realize linear table storage. Sequential storage definition The sequential storage structure of a linear list refers to a storage unit with consecutive addresses that stores […]

The modules used to build neural networks are added to the nn.Sequential() container in the order in which is passed into the constructor. import torch.nn as nn from collections import […]

data structure sequence table

1. Understand the sequence table A sequence table is a linear structure that uses a storage unit with a continuous physical address to store data elements in sequence. Generally, it is stored in an array. The addition, deletion, checking, and modification of data are completed on the array. 1.1 distinction Using simple language to describe […]

C++STL_vector sequence table

We must have come into contact with vector when we were learning data structures before. It is the sequence table in our data structure. We have implemented it using C language before. my_road: my code (gitee.com) This is the code I use to implement vector in C language; we have to write a lot of […]
