What are the inorder and postorder traversals of the following tree?

Question

With respect to the following tree:

1. What is the correct inorder traversal?

   1. U S T X C P Y R B A I G J F N H V T E D L
   2. U S T X C P Y R B A D E I G J F N H V T L

2. What is the correct postorder traversal?

   1. U T S X P R Y C B D I J G N V T H F E L A
   2. U T S X P R Y C B I J G N V T H F E D L A

I evaluated both pairs. But some are saying 1-1 and 2-1 are correct, while others say 1-2 and 2-2 are correct. I'm confused. Which ones are actually correct?

Answer 1

inorder:

B U S T X C P Y R A D E I G J F N H V T L

postorder (2.2 is correct):

U T S X P R Y C B I J G N V T H F E D L A
