Requirements / Prerequisites
- Students should possess a foundational understanding of various Data Structures, including arrays, linked lists, trees, and graphs.
- Prior exposure to common Algorithms such as searching, sorting, and basic graph traversal techniques is essential.
- Proficiency in at least one object-oriented programming language (e.g., Python, Java, C++) is mandatory for coding solutions.
- Familiarity with basic programming constructs like loops, conditionals, functions, and recursion is expected.
- A conceptual grasp of time and space complexity analysis (Big O notation) is required to evaluate algorithmic efficiency.
- Participants should be comfortable translating problem statements into executable code and debugging their solutions.
- This course assumes you have already learned the theory and are now ready to apply and test that knowledge rigorously.
- Basic problem-solving aptitude and a willingness to tackle challenging coding problems are highly beneficial.
- Access to a reliable internet connection and a coding environment (online or local IDE) is necessary for participation.
