Given an integer array nums where every element appears three times except for one, which appears exactly once. Find the single element and return it. You must implement a solution with a linear runtime complexity and use only constant extra space. For example, if the input is nums = [2,2,3,2], the output should be 3. Another example, if the input is nums = [0,1,0,1,0,1,99], the output should be 99. How do you solve this problem, considering edge cases like empty input, presence of zero, and negative numbers?

Let's explore the concept of FIFO (First-In, First-Out) depth in the context of data structures. What is FIFO depth, and why is it important to consider when designing and implementing a FIFO queue?** Explain how FIFO depth affects performance (latency and throughput), resource utilization (memory), and error conditions (overflow and underflow).** Can you provide a detailed example of a real-world scenario where FIFO depth is a critical parameter, like in a communication system or hardware design? For instance, if you are designing a system to process network packets, what factors would influence your choice of FIFO depth for the packet buffer? How does the arrival rate of packets, the processing time for each packet, and the acceptable packet loss rate play a role in determining the appropriate FIFO depth?** Also, discuss different strategies for managing FIFO depth dynamically based on system load and resource availability. How can adaptive FIFO depth control improve overall system performance and robustness?** What are some techniques to estimate the required FIFO depth analytically or through simulation?**

Let's explore your interest in Apple. To help me understand your motivations, please provide a detailed explanation of why you are specifically interested in working at Apple, rather than another technology company. Your answer should include specific examples related to Apple's products, services, culture, or values that resonate with you. For instance, you could discuss a particular Apple product that you admire and explain how its design or functionality aligns with your own interests and skills. Alternatively, you could talk about a specific initiative or project that Apple is undertaking and why you find it compelling. Furthermore, elaborate on how you believe your skills and experiences would contribute to Apple's success and how working here would support your professional growth and aspirations. Finally, please articulate how you see yourself fitting into Apple's culture and how you would embody the company's values in your day-to-day work. Please provide concrete examples to illustrate your points and demonstrate a deep understanding of Apple's unique position in the technology landscape.
