MAYBE

Problem:
 plus(0(),x) -> x
 plus(s(x),y) -> s(plus(x,y))
 times(0(),y) -> 0()
 times(s(x),y) -> plus(y,times(x,y))
 exp(x,0()) -> s(0())
 exp(x,s(y)) -> times(x,exp(x,y))
 ge(x,0()) -> true()
 ge(0(),s(x)) -> false()
 ge(s(x),s(y)) -> ge(x,y)
 tower(x,y) -> towerIter(0(),x,y,s(0()))
 towerIter(c,x,y,z) -> help(ge(c,x),c,x,y,z)
 help(true(),c,x,y,z) -> z
 help(false(),c,x,y,z) -> towerIter(s(c),x,y,exp(y,z))
