Find Second-Largest Element in Array (C#) | Brute → Better → Optimal | DSA for .NET Devs

In this interview-focused DSA session for .NET / C# developers, we solve: ✅ Find the Second Largest Distinct element in an integer array (C#) This is a common array pattern in product-based interviews—especially as a follow-up to “largest element”. We go step-by-step, interview-style: What you’ll learn How to handle distinctness (duplicates / repeated max values) 3 approaches you can explain confidently: Brute Force: Sorting-based approach Better: Two-pass scanning approach Optimal: Single-pass tracking (most interview-friendly) Clean handling of edge cases: all elements same duplicates negatives int.MinValue pitfalls Time & space complexity comparison Typical interviewer follow-ups + how to respond Interview mindset (what matters) Don’t just code—state constraints and clarify “distinct” Show stable logic for “not found” cases Communicate complexity tradeoffs clearly If you’re a working .NET dev aiming for product companies This series is built to make DSA approachable and interview-usable, without fluff. #CSharp #DotNet #DSA #CodingInterview #ArrayProblems #InterviewPreparation #ProductBasedCompanies #SoftwareEngineering
