Binary tree or Binary search tree print sum of leaf node

In this post we are learning about how to sum of all leaf binary tree or binary search tree BST nodes. Assume that following data are inserted on tree [517, 492, 553, 490, 507, 549, 567, 476, 528, 561].

sum of leaf node in given tree

Leaf node of tree has not contain any child nodes.
