Inorder Traversal of Binary Search Tree

 
To traverse a non-empty tree in inorder the following steps are followed recursively.
  • Visit the Root
  • Traverse the left subtree
  • Traverse the right subtree
The inorder traversal of the tree shown below is as follows.




Algorithm



The algorithm for inorder traversal is as follows.


Struct node
{
struct node * lc;
int data;
struct node * rc;
};


void inorder(struct node * root);
{
if(root != NULL)
{
inorder(root-> lc);
printf("%d\t",root->data);
inorder(root->rc);
}
}


So the function calls itself recursively and carries on the traversal.
