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.
