In Order Traversal In Binary Tree

  1. Its LNR ordered traversal.
  2. The order goes this way:
    1. L: Traverse the left sub tree.
    2. N: visit the node
    3. R: Traverse the right sub tree.
  3. Lets check with an example. Consider the following example.
      • Traverse the left sub tree of node 1
        • Traverse the left sub tree of node 2
          • Visit the node 4
        • Visit the node 2
        • Traverse the right sub tree of node 2
          • Visit the node 5
      • Visit the node 1
      • Traverse the right sub tree of node 1
        • Traverse the left subtree of node 3
          • Visit the node 6
        • Visit the node 3
        • Traverse the right sub tree of node 3
          • Visit the node 7
    2. On completing the traversal we get the in order if we follow the bolded nodes.
    3. In Order: 4 , 2 , 5 , 1 , 6 , 3 , 7

Traversal In A Binary Tree - Tree -3

Traversal In Binary Tree Traversing a binary tree means visiting each node of the tree exactly once. At each node : N : Visit the node L : Traverse its left subtree R : Traverse its right subtree These actions can be performed in any order... (3! = 6 different ways of ordering the three tasks.) Different orders: NRL NLR LNR LRN RNL RLN But we follow the convention which states left subtree to be traversed before right sub tree. Thus we are left with three orders: NLR , LNR and LRN The orders are named according the position of the node i.e., position of N in the order. pre : NLR in  : LNR post : LRN PRE ORDER TRAVERSAL: ( NLR ) N : Visit the node L : Traverse the left subtree R : Traverse the right subtree IN ORDER TRAVERSAL: ( LNR ) L : Traverse the left subtree N : Visit the node R : Traverse the right subtree ...

Trees - 2 Types: Strictly binary tree: Degree is every node either 0 or 2. Full Binary tree: Degree of every node is 2. Complete Binary Tree:A binary tree in which every level , exccept possibly the last , is completely filled and all nodes are as far left as possible. Array Representation of binary tree: Also called as sequential representation or linear representation We use 1D array Store the data with indexed 1 i.e., root node at Array[1](Even we can use 0 based index ) If a node is at index k in the array, its left child is at index 2k and right child at index 2k+1. If a node at index k then its parent is at index floor(k/2) The size of array needed to store a tree of height h is 2 h -1 Linked list representation : struct node { struct node *left; struct node *right; int data; } This structure can be used for the binary tree. Self referential structure where first and second...

Pre Order Traversal In Binary Tree Its NLR ordered traversal. The order goes this way: N: visit the node L: Traverse the left sub tree. R: Traverse the right sub tree. Lets check with an example. Consider the following example. Visit the node 1 Traverse the left sub tree of node 1 Visit the node 2 Traverse the left sub tree of node 2 Visit the node 4 Traverse the right sub tree of node 2 Visit the node 5 Traverse the right sub tree of node 1 Visit the node 3 Traverse the left subtree of node 3 Visit the node 6 Traverse the right sub tree of node 3 Visit the node 7 On completing the traversal we get the pre order if we follow the bolded nodes. Pre Order: 1 , 2 , 4 , 5 , 3 , 6 , 7
