MAYBE

Problem:
 cond1(true(),x,y) -> cond2(gr(y,0()),x,y)
 cond2(true(),x,y) -> cond2(gr(y,0()),p(x),p(y))
 cond2(false(),x,y) -> cond1(and(eq(x,y),gr(x,0())),x,y)
 gr(0(),x) -> false()
 gr(s(x),0()) -> true()
 gr(s(x),s(y)) -> gr(x,y)
 p(0()) -> 0()
 p(s(x)) -> x
 eq(0(),0()) -> true()
 eq(s(x),0()) -> false()
 eq(0(),s(x)) -> false()
 eq(s(x),s(y)) -> eq(x,y)
 and(true(),true()) -> true()
 and(false(),x) -> false()
 and(x,false()) -> false()
