Given the head of a singly linked list, group all the nodes with odd indices together followed by the nodes with even indices, and return the reordered list. The first node is considered odd, and the second node is even, and so on. Note that the relative order inside both the even and odd groups should remain as it was in the input. You must solve the problem in O(1) extra space complexity and O(n) time complexity. For example: Input: head = [1,2,3,4,5] Output: [1,3,5,2,4] Input: head = [2,1,3,5,6,4,7] Output: [2,3,6,7,1,5,4]

Let's talk about semaphores. Could you please explain what semaphores are, and how they are used in operating systems or concurrent programming? Provide examples of situations where semaphores are useful for controlling access to shared resources. Explain the difference between binary and counting semaphores. Furthermore, can you discuss potential problems that can arise when using semaphores, such as deadlocks or starvation, and how these problems can be addressed? For instance, consider a scenario where multiple threads need to access a database connection pool. How can semaphores be employed to manage access to the limited number of connections in the pool, preventing overuse and ensuring fair allocation among threads?

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.
