Progress Review for Days 21 & 22 and Strategic DevOps Roadmap Planning

Day 21: Tackling Binary Tree Problems

On Day 21, I focused on solving Medium-level problems related to Binary Trees. These problems helped me strengthen my understanding of DFS, BFS, and recursion. Here’s a quick rundown:

1. Binary Tree Right Side View 👀

   • Used BFS (level order traversal) to capture the last node at each level.

   • Explored DFS for an alternate approach.

2. Count Good Nodes in Binary Tree ✅

   • Applied DFS with a max-value tracking approach.

   • Ensured that at each node, if its value was greater than or equal to all previous nodes in the path, it was counted.

3. Validate Binary Search Tree (BST) 🌳

   • Implemented in-order traversal to verify if the tree followed the BST property.

   • Used min-max constraints for validation during recursion.

Overall, it was a productive day, reinforcing key tree traversal techniques.

Day 22: A Lazy Sunday Break 😴

After 20+ days of continuous problem-solving, I decided to take a well-deserved break on Day 22. Sometimes, stepping back helps in preventing burnout and allows for better learning retention.

Shifting Focus: DevOps & Cloud Engineering 🚀

While I’m still solving a couple of DSA problems here and there, my primary focus is now on DevOps & Cloud Engineering. Since I already have basic knowledge of the tools and technologies, it's crucial to plan my learning path properly to avoid getting overwhelmed.

A structured roadmap is the key to making steady progress without getting lost in the vast DevOps ecosystem. Here’s my initial breakdown:

🛠 Key Areas of Focus

1. Infrastructure as Code (IaC) – Terraform, CloudFormation

2. CI/CD Pipelines – Jenkins, GitHub Actions, ArgoCD

3. Containerization & Orchestration – Docker, Kubernetes, Helm

4. Monitoring & Logging – Prometheus, Grafana, ELK Stack

5. Cloud Services – AWS, GCP, Azure

6. Security & Compliance – IAM, Secrets Management, Network Policies

📅 Next Steps

• Finalizing a structured DevOps learning roadmap to stay on track.

• Hands-on practice with AWS, Kubernetes, and CI/CD pipelines.

• Continuing DSA practice at a reduced but steady pace.

Excited for this transition and the challenges ahead! 💪

Closing Thoughts

Shifting focus doesn’t mean completely abandoning DSA; it just means optimizing time for what matters most right now. By planning my DevOps learning path properly, I can ensure consistent progress without feeling overwhelmed.

Let’s keep building! 🚀🔥
