Applications of linked list data structure

  • Implementation of stacks and queues.
  • Implementation of graphs : Adjacency list representation of graphs is most popular which is uses linked list to store adjacent vertices.
  • Dynamic memory allocation : We use linked list of free blocks.
  • Maintaining directory of names.
