To revise algorithms for coding rounds quickly, focus on:

1. Core Algorithms: Prioritize mastering fundamental algorithms like sorting, searching, dynamic programming, and graph algorithms.

2. Practice: Solve a variety of problems on platforms like LeetCode and HackerRank to apply these algorithms and reinforce your understanding.

3. Patterns: Recognize common problem-solving patterns, such as sliding windows, greedy algorithms, and depth-first search, as they are frequently used in coding interviews.

4. Mock Interviews: Practice mock interviews to simulate real interview conditions and build confidence in your algorithmic skills.

5. Review Mistakes: Analyze your mistakes and learn from them. This iterative process will help you refine your problem-solving approach.

6. Time Management: Allocate focused time for daily revision and practice to maximize efficiency.

7. Ask Questions: Don't hesitate to seek help from peers, mentors, or online communities when you encounter challenging problems.

By concentrating on these key areas, you can efficiently prepare for coding rounds in a short time.
