Скачать или смотреть Day 10 DSA Challenge | Buy & Sell Stocks + Rearrange Array by Sign | Need Your Suggestion

Welcome to Day 10 of my DSA Challenge!
Today’s update is all about staying consistent, even when things don’t go as planned. I got a bit late uploading today’s video, so I wanted to share the reason honestly and continue the challenge with full energy.

Along with the update, I also solved two important array problems that are frequently asked in coding interviews and help build strong fundamentals.

🔥 Problems I Solved Today
1️⃣ Best Time to Buy & Sell Stock

This is one of the most popular interview questions.
I learned how to track the minimum price and calculate maximum profit efficiently using an optimized greedy approach. Understanding the logic behind this pattern helps a lot in future stock/array-based problems.

2️⃣ Rearrange Array Elements by Sign

This problem is great for practicing array manipulation and handling alternating positive-negative placements. It improves your control over indexing and teaches how to maintain order without using extra space (or with minimal space depending on the method used).

Both these problems pushed me to think better about time complexity, edge cases, and writing clean code.

💬 Need Your Suggestion

I’m confused about what to upload next and I want your help!
👉 Should I upload a full, detailed tutorial video on these problems?
OR
👉 Should I continue posting short daily update videos?

Your feedback really helps me shape this journey, so please drop your suggestion in the comments!
