Advanced Concepts
Other examples:
public static <X> List<X> add(X x, List<X> xs)
{ xs.add(x); return xs; }
public static void main(String[] args) {
List<Integer> xs = Arrays.asList(-1,-2,-1,0,1);
List<Integer> ys = reduce(xs,e,(vs,v) -> add(v+1,vs));
System.out.println(ys);
List<Integer> e = new ArrayList();
System.out.println(reduce(ys,xs,(vs,v) -> add(v,vs)));
}
Exercise: try to identify the result of each use of reduce
