MAYBE 'Pop* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { app(nil(), YS) -> YS , app(cons(X, XS), YS) -> cons(X, app(XS, YS)) , from(X) -> cons(X, from(s(X))) , zWadr(nil(), YS) -> nil() , zWadr(XS, nil()) -> nil() , zWadr(cons(X, XS), cons(Y, YS)) -> cons(app(Y, cons(X, nil())), zWadr(XS, YS)) , prefix(L) -> cons(nil(), zWadr(L, prefix(L)))} Proof Output: The input cannot be shown compatible
