Questions and Answers

What is a linked list in computer science?

  • A random arrangement of data elements in memory
  • A collection of nodes with no connections
  • A linear collection of data elements where each element points to the next (correct)
  • A data structure where each element contains data and a reference to a previous node

    • What allows for efficient insertion or removal of elements from any position in a linked list during iteration?

  • The structure of the linked list with nodes pointing to the next (correct)
  • The physical placement of elements in memory
  • The random arrangement of data elements
  • Additional links in the linked list

    • What is a drawback of linked lists in terms of data access time?

  • Data access time is a linear function of the number of nodes (correct)
  • Data access time decreases as the number of nodes increases
  • Data access time is constant regardless of the number of nodes
  • Data access time is logarithmic in relation to the number of nodes

    • What does each node in a linked list contain?
