Trees are simple to implement in J - https://code.jsoftware.com/wiki/User:Devon_McCormick/Trees - as are graphs - https://code.jsoftware.com/wiki/NYCJUG/2009-11-10/BreadthFirstGraphTraversal . A stack is simple to implement too but I'm not sure why you would want to as it's simply a vector with very restrictive rules to manipulate it. Linked lists make no sense in a language with dynamic arrays for much the same reason since a linked list is mainly a way of implementing dynamic arrays but has benefit only in a language which lacks these natively.
