I am not able to access the specific article you mentioned, but I can definitely help you with your query. If you're looking for a comprehensive list of data structures and algorithms relevant to each skill level in programming, you can follow a structured approach to practice competitive programming effectively.

Competitive programming requires a solid foundation in basic data structures and algorithms before moving on to more advanced topics. Here is a suggested step-by-step approach to practice competitive programming:

1. Basic Data Structures: Start by mastering fundamental data structures like arrays, linked lists, stacks, queues, and hash tables. Understand their operations, time complexity, and implementation details.

2. Basic Algorithms: Learn and implement basic algorithms such as sorting (e.g., bubble sort, insertion sort, merge sort, quicksort), searching (e.g., linear search, binary search), and basic graph algorithms (e.g., depth-first search, breadth-first search).

3. Intermediate Data Structures: Move on to more complex data structures like trees (binary trees, binary search trees, heaps), graphs (directed and undirected graphs, weighted graphs), and advanced data structures like segment trees, fenwick trees, and trie.

4. Intermediate Algorithms: Expand your algorithmic knowledge with more advanced algorithms, including dynamic programming, graph algorithms (e.g., Dijkstra's algorithm, Bellman-Ford algorithm), and string algorithms (e.g., pattern matching, string manipulation).

5. Advanced Data Structures: Study advanced data structures such as AVL trees, B-trees, disjoint-set union (DSU), suffix trees, and advanced graphs (e.g., topological sorting, minimum spanning trees).

6. Advanced Algorithms: Explore advanced algorithms like advanced dynamic programming techniques (e.g., memoization, bottom-up approach), advanced graph algorithms (e.g., Tarjan's algorithm, Floyd-Warshall algorithm), and advanced string algorithms (e.g., Knuth-Morris-Pratt algorithm, Z algorithm).

Remember that competitive programming is not just about learning data structures and algorithms but also about problem-solving skills. Practice regularly by participating in coding contests and solving problems from online platforms like Codeforces, LeetCode, and HackerRank.

While I can provide you with guidance, it's essential to consult various resources such as textbooks, online tutorials, and coding platforms to deepen your understanding of each topic. Always cite your sources and avoid copying content directly to maintain academic integrity and avoid plagiarism. Good luck with your competitive programming journey!

Introduction:

Competitive programming has emerged as a popular sport among coding enthusiasts, challenging their problem-solving skills and algorithmic thinking. Among the various platforms available, Codeforces stands out as a prominent online judge and community for competitive programmers worldwide. Whether you are a beginner or an experienced programmer, Codeforces provides a rich environment to hone your skills, compete with others, and learn from the best. In this blog, we will explore the key features of Codeforces and how to make the most out of this platform to enhance your competitive programming journey.

1. Problem Sets and Contests: One of the main attractions of Codeforces is its extensive collection of problem sets and regular contests. Codeforces hosts numerous contests, ranging from educational rounds to official championship events. Participating in these contests allows you to solve challenging problems, compete against other programmers, and improve your ranking. Additionally, the contests are often rated, enabling you to track your progress and measure your performance.

2. Rating System: Codeforces employs a rating system that assigns a numerical value to each participant based on their performance in contests. The rating reflects your skill level and helps in assessing your progress over time. As you participate in more contests and solve problems, your rating will be adjusted accordingly, providing a tangible measure of your improvement. This rating system adds a competitive element to the platform and motivates programmers to strive for higher rankings.

3. Practice Section: The practice section in Codeforces is a treasure trove of problems categorized according to their difficulty levels and topics. It allows you to solve problems individually, understand different algorithms and data structures, and learn new techniques. You can filter problems based on your preferred programming language, tags, and rating range, making it easier to find relevant practice material. Regularly solving problems in the practice section not only enhances your problem-solving skills but also helps you grasp new concepts.

4. Virtual Contests: In addition to the live contests, Codeforces offers virtual contests that enable you to participate in previous contests as if they were happening in real-time. This feature allows you to experience the contest environment, solve problems, and compare your performance with other participants who have already completed the contest. Virtual contests are an excellent way to practice under time constraints and improve your speed and accuracy.

5. Community and Discussions: Codeforces boasts a vibrant community of programmers from all around the world. The platform allows you to interact with fellow enthusiasts, ask questions, and seek guidance on problem-solving approaches. The discussion forums are a valuable resource where experienced programmers share their insights and provide explanations for various contest problems. Engaging with the community not only broadens your knowledge but also helps you develop a strategic mindset and learn alternative problem-solving techniques.

6.** Educational Content**: Apart from its extensive problem sets and contests, Codeforces also offers educational content to help you grasp fundamental concepts and enhance your coding skills. The educational section includes tutorials, articles, and video lectures on various topics such as algorithms, data structures, and programming techniques. This wealth of resources caters to programmers of all levels, ensuring a continuous learning experience.

Conclusion:

Codeforces serves as a comprehensive platform for competitive programmers to test their skills, compete with peers, and engage with a supportive community. Through its problem sets, contests, rating system, practice section, and educational content, Codeforces offers a holistic learning experience that fosters growth and improvement.
