My main purpose was only to make him aware of the definition of
inorder , if he does
not know what does inorder means , then design recipe is not going to
help anyway,
unless he tries all the combinations.From his code i am 100% sure if he knew
what inorder means , he would have solved the problem.

Sorry , if it was terrible suggestion , i thought otherwise.
