Which data structure is most suitable for implementing an LRU (Least Recently Used) cache?

An LRU (Least Recently Used) cache is most efficiently implemented using a combination of a HashMap and a Doubly Linked List. The HashMap provides O(1) access to cache entries, while the Doubly Linked List maintains the order of usage, allowing for quick updates to the most recently and least recently used elements.
Regarding Binary Trees, which of the following is true? When does the Dijkstra's algorithm fail to find the shortest path in a graph? The time complexity of finding a shortest path in a network is: What is the name of a linear collection of data components where the linear node is provided by a pointer? Which type of algorithms are applicable to scheduling resources in operating systems? What is the time complexity of inserting an element into a Binary Search Tree (BST) in the worst case? Where is a heap data structure typically used? When we attempt to add the eleventh element to a stack with a size of 10, we encounter a circumstance known as: Which of the following are true about the Weiner filter? Which data structure is most suitable for implementing an LRU (Least Recently Used) cache? How much time would it take to add an element to the linked list asymptotically? Why is the space complexity of a recursive algorithm often higher than its iterative counterpart?
