Medium Level Questions
These questions are balanced in difficulty and test your problem-solving skills with more complex scenarios.
What to Expect in Medium Questions
- More complex data structures like trees, graphs, and advanced hash maps
- Dynamic programming, BFS/DFS, and greedy algorithms
- Optimization challenges with time/space complexity tradeoffs
- Solutions typically require careful planning and algorithm selection
- Suitable for candidates with solid programming experience

- 2Master dynamic programming through incremental practice
- 3Practice both recursive and iterative solutions
- 4Analyze space-time complexity tradeoffs in your solutions
Time Management
For medium questions, you should aim to:
Understanding the problem3-5 min
Planning your approach5-10 min
Coding the solution10-20 min
Testing & refining5-10 min
In a typical interview setting, you should be able to completely solve a mediumquestion in 20-30 minutes.
