1. Introduction When using Map in daily development, we often encounter many complex processing scenarios, such as: Map with multiple keys, not only the value can be obtained based on the key, but also the key can be obtained based on the value without traversing, Map with repeated keys, numbers and other ranges Mapping the […]

The use of set/multiset and map/multimap in C++
Associative container In the preliminary stage, we have already been exposed to some containers in STL: For example: vector, list, deque, forward_list (C++11), etc. These containers are collectively called sequential containers because their underlying data structure is a linear sequence data structure, and the elements themselves are stored in them. The containers we want to […]
4.7.10-Testing_for_IMAP_SMTP_Injection
Testing for IMAP SMTP Injection ID WSTG-INPV-10 Summary This threat affects all applications that communicate with mail servers (IMAP/SMTP), generally webmail applications. The aim of this test is to verify the capacity to inject arbitrary IMAP/SMTP commands into the mail servers, due to input data not being properly sanitized . The IMAP/SMTP Injection technique is […]

＜STL – 3＞ Dictionary map and multimap
1. Introduction Introduction to map Map is a standard Associative container. A map is a sequence of key-value pairs, that is, (key, value) pairs. It provides fast retrieval capabilities based on key The key value in the map is unique, and the elements in the dictionary are arranged in a certain order Map can directly […]

map, multimap and unordered_map (hash_map) and unordered_multimap
一、hash_map & amp; unordered_map hash_map is unordered_map Chinese standard library: unordered_map Search, insertion and element removal have average constant time complexity. Elements are not ordered in any particular order internally , but are organized into buckets. Which bucket an element goes into depends entirely on the hash of its key. This allows fast access to […]
[Qt] Understanding the associated containers QMap, QMultiMap, QHash, and QMultiHash in Qt
In Qt, there are several associative containers to choose from: QMap: QMap is an associative container that stores key-value pairs and automatically sorts them based on the key. It provides fast find and insert operations and is suitable for scenarios where sorting and searching based on keys are required. QMultiMap: QMultiMap is an associative container, […]
map/multimap container
1 Basic concepts of map Introduction: All elements in map are pairs The first element in the pair is key (key value), which serves as an index, and the second element is value (real value). All elements are automatically sorted based on the element’s key value Essence: Map/multimap is an associative container, and the underlying […]
