Linked List V/S Binary Search Tree

March 19, 2014 by Dhaval Dave

Linked List :

Node(1) -> Node(2) -> Node(3) -> Node(4) -> Node(5) -> Node(6) -> Node(7)
  • In linked list, the items are linked together through a single next pointer.
  • Next Node’s Key Can be larger or samller then previous Node.
  • Not Sorted
  • Time Complexity of Search :O(n) Insert : O(1) Delete : O(1) {if you have use optimized method }


Binary Search Tree:

           [4]
          /   \
       [2]     [6]
      /  \    /   \
    [1]  [3] [5]   [7]
  • In a binary tree, each node can have 0, 1 or 2 sub nodes.
  • The key of the left node is lesser than the key of the node and the key of the right node is more than the node
  • Sorted
  • Time Complexity of Search : O(log(n)) Insert : O(log(n)) Delete : O(log(n))
