"WebIf a binary tree is traversed in-order, the output will produce sorted key values in an ascending order. We start from A, and following in-order traversal, we move to its left subtree B. B is also traversed in-order. The process goes on until all the nodes are visited. The output of inorder traversal of this tree will be − D → B → E → A → F → C → G " - Binary tree post order traversal
