Nice answers Raul, Ric and David. I don't know how I got so confused.
Here's what I put together:
g 5
1 2 3 4 5 4 3 2
g
[: >: [: ((] , -) i.) <:
h 5
1 2 3 4 5 4 3 2
h
[: >: <: (] , -) [: i. <:
i 5
1 2 3 4 5 4 3 2
i
[: >: [: (] (] , -) i.) <:
5!:4 <'g'
-- [:
+- >:
│ -- [:
--+ │ -- ]
│ │ -----+- ,
L----+----+ L- -
│ L- i.
L- <:
5!:4 <'h'
-- [:
+- >:
│ -- <:
--+ │ -- ]
│ +----+- ,
L----+ L- -
│
│ -- [:
L----+- i.
L- <:
5!:4 <'i'
-- [:
+- >:
│ -- [:
--+ │ -- ]
│ │ │ -- ]
L----+----+----+- ,
│ │ L- -
│ L- i.
L- <:
I like the tree for h besst.

Along with the other answers, let's specifically observe that
((],-)i.)
is a hook with the two verbs (],-) and i. .
j evaluates the monad integers then the train (],-) as a dyad with the
result of integers as the y argument.
