20. Master Stock Span in ONE Pattern — Amazon Stack Question Made Easy | Stock Span Problem

In this video, you’ll master the Stock Span Problem using a Stack — the pattern behind many top coding interviews at Amazon, Microsoft, and Google. Most students try brute force and fail. In this lesson, I break down the monotonic stack logic step-by-step, dry-run every case, and show you exactly how the algorithm “thinks.” You will learn: • Why brute force is wrong • Why stack is the right tool • How to maintain a decreasing stack • How to compute span in O(N) time • Full dry run on the classic example • How this pattern appears in many DSA problems 🔹 Sample Input Used in Video 100 80 60 70 60 75 85 🔹 Final Output 1 1 1 2 1 4 6 If you want to crack interviews and actually understand stacks (not memorize them) — this video is for you. 📌 Subscribe & follow the playlist to build DSA the right way — from the system level.    • DSA with Java   ━━━━━━━━━━━━━━━ 📌 Timestamps ━━━━━━━━━━━━━━━ 00:00 – Problem Statement 02:08 – Dry Run 05:29 – Full Code Begins 05:33 – calculateStockSpan() Method 11:24 – main() Method 12:57 – Output 13:03 – Outro ━━━━━━━━━━━━━━━ 💡 Connect with me ━━━━━━━━━━━━━━━ If you love clear DSA explanations, subscribe for more. #MinimumStack #DataStructures #Java #CodingInterviews #FAANG #DSA #Stack 👍 If this helped you: Like the video Subscribe for DSA explained clearly Comment “STACK” for more problems If this helped you, *LIKE 👍 | SUBSCRIBE 🔔 | SHARE* with your study group!
