MAYBE

Problem:
 times(x,y) -> help(x,y,0())
 help(x,y,c) -> if(lt(c,y),x,y,c)
 if(true(),x,y,c) -> plus(x,help(x,y,s(c)))
 if(false(),x,y,c) -> 0()
 lt(0(),s(x)) -> true()
 lt(s(x),0()) -> false()
 lt(s(x),s(y)) -> lt(x,y)
 plus(x,0()) -> x
 plus(0(),x) -> x
 plus(x,s(y)) -> s(plus(x,y))
 plus(s(x),y) -> s(plus(x,y))
