Prefix Sum Interview Patterns | Subarray Sum + Longest Subarray | Python DSA Binge

If you’re preparing for coding interviews, prefix sum is one of the most important array patterns you must master. In this binge video, we cover two must-know prefix sum interview problems in one place: • Subarray Sum Equals K (counting subarrays) • Longest Subarray with Given Sum (maximum length logic) Both problems use the same prefix sum + hashmap pattern but test your thinking in different ways. This pattern is frequently asked in service companies, product companies, and online assessments. We explain everything step by step with: • clear logic • dry run • interview explanation • clean Python code This video is part of the DSA Coding for Placements (Python) playlist.
