      Inorder (L → Root → R)Always Sorted!
      [20, 30, 40, 50, 60, 70, 80]
      Preorder (Root → L → R)
      [50, 30, 20, 40, 70, 60, 80]
      Postorder (L → R → Root)
      [20, 40, 30, 60, 80, 70, 50]
      Invariant Property:

      For any node N in a Binary Search Tree, all keys in the left subtree satisfy key < N.val, and all keys in the right subtree satisfy key > N.val. This property guarantees that an Inorder Traversal produces strictly sorted elements in O(N) time!
