Card 1
Question: What is the primary difference between how arrays and linked lists store elements?
Answer: Arrays store elements in contiguous memory locations, while linked lists store elements non-contiguously.
Card 2
Question: What does each element in a linked list contain?
Answer: Each element (node) contains data and a reference or 'pointer' to the next node in the sequence.
Card 3
Question: What are the core components of a linked list?
Answer: The core components are the node and the pointer.
Card 4
Question: What are the two main parts of a node in a linked list?
Answer: A node typically consists of a data field and a pointer (or reference) field.
Card 5
Question: What is the purpose of the data field in a node?
Answer: The data field stores the actual information or value that the node represents.
Card 6
Question: What is the purpose of the pointer field in a node?
Answer: The pointer field stores the memory address of the next node in the sequence, linking one node to the next.
Card 7
Question: What value does the pointer field of the last node in a singly linked list typically hold?
Answer: The pointer field of the last node typically holds a special value, often `null` or `nil`, indicating the end of the list.
Card 8
Question: In the context of linked lists, what is a pointer?
Answer: A pointer is a variable that stores a memory address.
Card 9
Question: What does the 'head' pointer in a linked list point to?
Answer: The 'head' pointer points to the first node of the list.
Card 10
Question: What is a singly linked list?
Answer: A singly linked list is the simplest form of a linked list where each node contains a data field and a single pointer field that points to the next no
