Binary search tree print leaf nodes using recursion

In this post we are learning about how to print leaf BST nodes.Assume that following data are inserted on tree [587, 523, 589, 509, 582, 600, 436, 517, 578, 478].

BST Tree Binary Search Tree 587523509436589582478578517600

Leaf node of tree has not contain any child nodes.

In this execution process not imagination all steps. below link click and view how to insert bst node, how to show all bst node and how to print leaf BST nodes.

C program to print all leaf nodes of given binary search tree. recursive approach.

Output
 BST Inorder data is :  436  478  509  517  523  578  582  587  589  600
 Leaf Nodes is : 478 517 578 600
