Accessing an element by index in a linked list requires O(n) time, as it must traverse the list from the head.

Accessing an element by index in a linked list requires O(n) time, as it must traverse the list sequentially.

Accessing an element by index in a linked list requires traversal from the head, making it O(n) in time complexity.

Traversal of an AVL tree is O(n) because it visits every node, while insertion, deletion, and searching are O(log n).

Sorting the nodes is not an operation performed during the insertion in a Red-Black tree.

Sorting the tree is not an operation performed during the insertion of a node in a Red-Black tree; the tree remains a binary search tree.

Traversal is not a specific operation unique to Red-Black trees; it is a general operation applicable to all tree structures.

The 'Pop' operation is not supported by a queue; it is associated with stacks. Queues use 'Enqueue' to add and 'Dequeue' to remove elements.

A standard stack supports push, pop, and peek operations, but does not support dequeue, which is an operation specific to queues.

The 'Push' operation is associated with stacks, while queues use 'Enqueue' to add and 'Dequeue' to remove elements.

Dequeue is not associated with a stack; it is an operation related to queues.

Enqueue is an operation associated with queues, while stacks use push, pop, and peek operations.

Sorting is not a direct operation performed on a tree; trees are often used to facilitate sorting.

Linked lists do not support direct access by index, which is a characteristic of arrays.

Rotations (single or double) are performed to maintain the balance of an AVL tree after insertions or deletions.

After an insertion in an AVL tree, rotations (single or double) are performed to maintain the balance property.

Removing an element (pop for stacks and dequeue for queues) is typically O(1) for both data structures.

Searching for an element in a linked list requires traversing the list, which takes O(n) time.

All operations (Push, Pop, and Peek) on a stack are performed in constant time, O(1).

Dead code elimination is an optimization technique that can be applied to intermediate code to remove code that does not affect the program's output.

Stochastic Gradient Descent (SGD) is a widely used optimizer for training neural networks.

Adam (Adaptive Moment Estimation) adapts the learning rate based on the first and second moments of the gradients.

LR parsing can handle a larger class of grammars compared to LL parsing, including all deterministic context-free grammars.

The minimum spanning tree can be solved using a greedy algorithm, while the knapsack problem is not always solvable by greedy methods.

BFS can be used to find connected components in an unweighted graph by exploring all reachable vertices from a starting vertex.

DFS can be used for finding paths in a maze and topological sorting, but not for finding the shortest path in a weighted graph.

The Fibonacci sequence can be efficiently calculated using dynamic programming by storing previously computed values to avoid redundant calculations.

All of the above problems can be solved using recursion.

In a Red-Black tree, all leaves (NIL nodes) are black, not red.

In Red-Black trees, all leaves (NIL nodes) are black, not red. This is one of the properties that helps maintain balance.
