📣 What Inspired This Series? The inspiration came from the real questions I encountered while preparing for Python interviews! 💡 I decided to use the Feynman Learning Technique— “learning by teaching”—to solidify my understanding through explanation. While organizing and sharing, I hope to: 🔹 Help myself└── Clear knowledge gaps → Strengthen theoretical foundations → Understand … Read more
What are Bit Fields? Imagine you are moving and have many small items: a few screws, some bottle caps, and a few coins. If you use a huge moving box for each item, it can hold them, but it wastes a lot of boxes, and the moving truck won’t fit many boxes.Bit fields are the … Read more

IntroductionHello everyone, today I want to bring you a different topic:Disjoint Set👇 01Concept of Disjoint SetA disjoint set is a data structure that can dynamically maintainseveral non-overlapping sets, supporting merging and querying.The operations of a disjoint set generally consist ofthree steps: 1 Initialize each point's set to itself. Generally, this step only needs to be … Read more
01 The data structure that is independent of the computer used is the A. Storage structure B. Logical structure C. Physical structure D. Physical and storage structure Answer: B Explanation: Brief 02 Among the following statements, the incorrect one is: A. The storage structure of data is closely related to the efficiency of data processing … Read more
In C++, a linked list is a dynamic data structure composed of a series of nodes, each containing a data field and a pointer field (pointing to the next adjacent node). Unlike arrays that use contiguous memory, linked list nodes are stored in non-contiguous memory, linked together by pointers, thus providing flexible insertion/deletion features. 1. … Read more
What is the collections module? When writing Python, you definitely rely on built-in containers like <span>list</span>, <span>dict</span>, and <span>tuple</span>. But did you know that there is a “comprehensive collection of containers” hidden in the standard library—<span>collections</span>? It acts like a B-level enhancement patch for Python’s native containers, providing a bunch of advanced data structures specifically … Read more
Sets are an unordered data structure with unique elements that can be created in specific ways, allowing for deduplication and various operations between sets. They are commonly used data tools that handle element uniqueness and set relationships. 01 Sets The corresponding data structure for sets in Python is set, and its basic usage is as … Read more
(Pre-view Tip: The code in this article is run using PyCharm) (Content is concise, reading time is only a few minutes) 0 1 What is a List A list consists of a series of elements arranged in a specific order. In the variable stage, we can assign any content to a variable, allowing the variable … Read more
In C++, a List is essentially a doubly linked circular list with a head node. Sounds a bit convoluted, right? Many friends struggle to understand the difference between List and vector when they first learn about it… Please take a look at this image 👇 Image: A doubly linked circular list with a head node, … Read more
