hi all, not sure if there is someone still working during holiday like me :
I got a little problem in implementing some operations on tree.
suppose we have a tree date type defined:
data Tree a = Leaf a | Branch (Tree a) (Tree a)
I want to do a concatenation on these tree just like the concat on list.
Anyone has idea on it? or there are some existing implementation?
Thank you and Happy New Year!
