Frequently Asked Questions

What DSA topics does Phantom Code help with during interviews?

Phantom Code covers all major DSA topics including two pointers, sliding window, binary search variants, graph BFS/DFS, dynamic programming, greedy algorithms, heaps/priority queues, tries, and advanced string algorithms.

How does Phantom Code identify the right approach for DSA problems?

Phantom Code uses pattern recognition to identify the problem type (sliding window, two pointer, BFS/DFS, DP, etc.) and applies the optimal approach with step-by-step explanation of why that approach works.

Does Phantom Code provide complexity analysis for DSA solutions?

Yes. Every solution includes time and space complexity with clear explanations of why — not just the big-O notation. This helps you discuss trade-offs confidently during the interview.

Can Phantom Code handle edge cases in DSA problems?

Yes. Phantom Code identifies and handles edge cases that interviewers specifically look for, such as empty inputs, single elements, duplicates, negative numbers, and overflow conditions.

How fast does Phantom Code generate DSA solutions during interviews?

Phantom Code generates complete DSA solutions with approach, code, and complexity analysis in seconds — fast enough for real-time use during live technical interviews.
