How do you traverse a singly linked list in reverse using O(1) memory?

Data Structures & AlgorithmsMedium

You are given a singly linked list. How do you traverse it in reverse order using O(1) memory? For example, given the list 1 -> 2 -> 3 -> 4 -> null, your traversal should output 4, 3, 2, 1. Explain your approach and provide a code example. Consider the constraints of not modifying the linked list structure itself. Can you adapt your approach if modifying the list structure is permitted, and what would be the trade-offs?

How would you design a thread-safe LRU cache with O(1) get and put operations?

System DesignHard

Let's design a cache. Consider the following requirements: Basic Functionality: Implement a cache with put(key, value) and get(key) methods. Eviction Policy: Implement an LRU (Least Recently Used) eviction policy. When the cache is full, the least recently accessed item should be evicted to make space for the new item. Thread Safety: Ensure the cache is thread-safe to handle concurrent access from multiple threads. Generics: The cache should be able to store any type of key and value (using generics). Time Complexity: get and put operations should have an average time complexity of O(1). Example Usage: Cache cache = new Cache(5); // Cache with capacity 5 cache.put(1, one); cache.put(2, two); cache.get(1); // Access key 1, moves it to the most recently used cache.put(3, three); cache.put(4, four); cache.put(5, five); cache.put(6, six); // This will evict key 2 (LRU) System.out.println(cache.get(2)); // Output: null (because it was evicted) Discuss the data structures you would use, the implementation details for each method, and how you would address thread safety.
