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?

Describe your proudest project. What were the challenges, and what was your specific role in overcoming them? Elaborate on the technologies used, the impact the project had, and what you learned from the experience. For example, if you developed a new feature for a popular app, explain how it improved user engagement or solved a specific problem for users. Or, if you automated a critical business process, describe how it increased efficiency and reduced errors. If you led a project, explain how you motivated the team and overcame interpersonal challenges. Be sure to highlight your specific contributions and quantify the results whenever possible, showcasing the positive outcomes you helped achieve.
