Describe the difference between a stack and a queue. Provide an example of when you might use each data structure. Write functions to implement the push and pop methods for a stack and the enqueue and dequeue methods for a queue. Explain the time complexity of each of these operations. Additionally, discuss a scenario where you might need to implement a stack using a queue or a queue using a stack.

Let's design a system to efficiently manage meeting room bookings for a large company. Consider the following: Scalability: The system should handle a large number of meeting rooms and employees. Concurrency: Multiple users should be able to book rooms simultaneously without conflicts. Features: Room availability search based on time, date, and number of attendees. Recurring meeting support. Integration with employee calendars (e.g., Google Calendar, Outlook). Conflict detection and resolution. Reporting and analytics (e.g., room utilization). Example: Imagine a company with 100 meeting rooms and 5000 employees. A user wants to book a room for a daily stand-up meeting with 10 attendees, recurring every weekday for the next month. How would your system handle this request, ensuring no double bookings and updating the user's calendar? Specifically, discuss the system architecture, data models, key algorithms, and potential bottlenecks. How would you address these bottlenecks to ensure the system remains responsive and reliable?

Let's say you are managing a team of five engineers working on a critical feature for an upcoming product launch. One of your engineers, Sarah, consistently delivers high-quality work but has been missing deadlines lately. During a one-on-one meeting, Sarah confides in you that she is feeling overwhelmed with her workload due to personal issues outside of work. Additionally, another engineer, David, has been expressing frustration about the lack of clear direction and feeling that his skills are not being fully utilized. Furthermore, the team is starting to experience conflicts regarding code ownership and integration, leading to delays and tension. As the engineering manager, how would you address these issues to ensure the successful delivery of the feature while maintaining a positive and productive team environment? Please provide specific steps and strategies you would implement to handle each situation, including Sarah's performance, David's concerns, and the team's conflict.
