You are given a list of integers. Modify the list in-place such that all even numbers appear at the beginning of the list and all odd numbers appear at the end. The relative order of even numbers and odd numbers does not matter. For example: If the input list is [3, 1, 2, 4, 6, 7], a valid output would be [2, 4, 6, 3, 1, 7]. Another valid output would be [4, 2, 6, 1, 3, 7]. The even numbers (2, 4, 6) are at the beginning, and the odd numbers (3, 1, 7) are at the end. If the input list is [1, 3, 5, 7], the output should be [1, 3, 5, 7] since all numbers are already odd. If the input list is [2, 4, 6, 8], the output should be [2, 4, 6, 8] since all numbers are already even. If the input list is [], the output should be []. Write a function that takes a list of integers as input and modifies it in-place to satisfy these conditions. Your solution should be efficient, ideally completing the modification in O(n) time complexity and O(1) space complexity.

Let's delve into the realm of networking. Imagine you are tasked with designing a network for a growing company with three distinct departments: Engineering, Marketing, and Sales. Each department has unique needs and security requirements. The Engineering department requires high bandwidth for data transfer and code compilation, the Marketing department needs access to various social media platforms and marketing tools, and the Sales department needs secure access to customer data and CRM systems. Furthermore, the company wants to implement a guest network for visitors. The network should be designed with scalability, security, and performance in mind. Considering these requirements, address the following: Describe the network topology you would choose and why. Explain the advantages and disadvantages of your chosen topology in this scenario. Outline the IP addressing scheme you would implement. Include subnetting details and justification for your choices. Discuss the security measures you would implement to protect each department's data and ensure network security. Elaborate on firewall rules, access control lists (ACLs), and intrusion detection/prevention systems (IDS/IPS). Explain how you would segment the network to isolate the guest network from the internal network. What specific technologies or configurations would you use to achieve this? Describe how you would ensure high availability and redundancy in the network design. What measures would you take to prevent single points of failure? Outline the routing protocols you would use and why. How would you configure them to optimize network performance and ensure efficient data delivery? Discuss how you would monitor and manage the network to ensure optimal performance and security. What tools and techniques would you employ for network monitoring and troubleshooting?

Tell me about your best project. To provide a comprehensive overview, please address the following points: Project Overview: What was the project's purpose and goals? What problem did it solve or what opportunity did it address? Who was the target audience or end-user? Your Role and Responsibilities: Describe your specific role within the project team. What were your key responsibilities and contributions? Did you lead any specific aspects of the project? If so, elaborate. Technical Details: What technologies, languages, and frameworks did you use? Describe the architecture and design of the system. Were there any interesting or challenging technical aspects? Challenges and Solutions: What were the major challenges you faced during the project? How did you overcome these challenges? Be specific about the solutions you implemented. Did you have to make any trade-offs or compromises? Explain why. Outcomes and Impact: What were the measurable outcomes of the project? How did the project impact the organization or its users? Did the project achieve its intended goals? Lessons Learned: What did you learn from this project? What would you do differently if you were to undertake a similar project again? How has this project influenced your approach to software development? For example, if you developed an e-commerce platform, you might discuss how you implemented a scalable microservices architecture to handle high traffic, or how you used machine learning to personalize product recommendations. Be prepared to discuss technical details, challenges you faced, and the impact your project had on the users or the business. Focus on projects where you played a significant role and can demonstrate your technical skills and problem-solving abilities.
