Extract the first $10$ unique letters from your full name in a sequential order, ignoring

duplicates, spaces, and dot. If your full name has fewer than $10$ unique letters,

concatenate the word 'UNIVERSITY' to reach the required number. Construct a

complete binary tree using these $10$ unique letters $($uppercase$).$ Apply Inorder,

Preorder, and Postorder tree traversals methods on the complete binary tree and state

the sequence of the nodes.
