We can traverse the tree starting from the root level and keep curr_level of the node.
Increment the curr_level each time we go to left or a right subtree.
Return the max depth of an odd level,if it exists.
1) return 0 if curr_node == NULL
2) if curr_node is leaf and curr_level is odd,
3) else maximum(depthOdd(left subtree),
Let us create Binary Tree shown in above example */
Node root = newNode(10);
root.left = newNode(28);
root.right = newNode(13);
root.right.left = newNode(14);
root.right.right = newNode(15);
root.right.right.left = newNode(23);
root.right.right.right = newNode(24);
