It seems like you're asking for the post-order traversal of a binary tree given the pre-order and in-order traversals. Here's how you can do it:

1. The first element of the pre-order traversal (A) is the root of the tree.
2. In the in-order traversal, the elements to the left of the root (D B G E H) are in the left subtree, and the elements to the right of the root (C F) are in the right subtree.
3. Repeat the process for each subtree. For the left subtree, B is the root, D is to its left, and G E H are to its right. For the right subtree, C is the root and F is to its right.
4. Continue this process until each subtree only has one element.
5. The post-order traversal is obtained by visiting the left subtree, then the right subtree, and finally the root.

So, the post-order traversal of the given binary tree is: D H G E B F C A.
