* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            group3(l) -> group3#1(l)
            group3#1(cons(x,xs)) -> group3#2(xs,x)
            group3#1(nil()) -> nil()
            group3#2(cons(y,ys),x) -> group3#3(ys,x,y)
            group3#2(nil(),x) -> nil()
            group3#3(cons(z,zs),x,y) -> cons(tuple#3(x,y,z),group3(zs))
            group3#3(nil(),x,y) -> nil()

            zip3#2(nil(),l3,x,xs) -> nil()
            zip3#3(cons(z,zs),x,xs,y,ys) -> cons(tuple#3(x,y,z),zip3(xs,ys,zs))
            zip3#3(nil(),x,xs,y,ys) -> nil()
        - Signature:
            {group3/1,group3#1/1,group3#2/2,group3#3/3,zip3/3,zip3#1/3,zip3#2/4,zip3#3/5} / {cons/2,nil/0,tuple#3/3}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {group3,group3#1,group3#2,group3#3,zip3,zip3#1,zip3#2
            ,zip3#3} and constructors {cons,nil,tuple#3}
