Algo Ace 2.0 – Session 02 -The Hidden Algorithms Behind Real Systems Speaker: Mr. Harsha Weerasinghe Date: 06th June 2026 Time: 7.00 PM Onwards Platform : Virtual Overview Algo Ace 2.0 Session 02 was conducted with the objective of demonstrating how fundamental algorithmic patterns are applied in real-world systems and technologies. Building upon the foundations established in Session 01, this session focused on connecting competitive programming concepts with practical applications used in modern software and data processing systems. Session Highlights The session introduced participants to several widely used algorithmic patterns and explored how these concepts appear in real-world platforms and engineering systems. Topics covered included: • Frequency counting using Hash Maps and its relationship to GROUP BY operations in databases. • Prefix Sum techniques and their applications in efficient range processing. • Two Pointer techniques for optimized traversal and searching. • Sliding Window methods used in real-time computations and analytics. • Ordering and ranking concepts through structured processing using ROW_NUMBER() and related approaches. The speaker used practical examples and industry-inspired scenarios to demonstrate how these patterns help build efficient and scalable systems. Participant Engagement Participants actively engaged throughout the session and participating in the interactive quiz segment conducted at the end of the session. The session encouraged delegates to view algorithmic concepts not only as competitive programming techniques but also as tools used in real-world software engineering. Conclusion Session 02 successfully bridged the gap between algorithmic thinking and real-world engineering applications. By showcasing how common programming patterns power modern systems, the session provided participants with valuable insights into the practical relevance of competitive programming concepts and strengthened their problem-solving mindset for future learning opportunities.
