Preorder traversal is a kind of dfs 3. BFS is sequence traversal, which can be realized by the characteristics of queues 4. Middle order traversal is a sort of binary search tree nodes from small to large 5. Height calculation can be realized by pre order traversal 6.

ETE implements the three most common strategies: preorder, levelorder and postorder. The following scheme shows the differences in the strategy for visiting nodes (note that in both cases the whole tree is browsed): preorder: 1)Visit the root, 2) Traverse the left subtree , 3) Traverse the right subtree. Here you will get program for binary search tree in C. A Binary Search Tree (BST) is a binary tree in which all the elements stored in the left subtree of node x are less then x and all elements stored in the right subtree of node x are greater then x.
