MAYBE

Problem:
 minus(0(),x) -> 0()
 minus(s(x),0()) -> s(x)
 minus(s(x),s(y)) -> minus(x,y)
 mod(x,0()) -> 0()
 mod(x,s(y)) -> if(lt(x,s(y)),x,s(y))
 if(true(),x,y) -> x
 if(false(),x,y) -> mod(minus(x,y),y)
 gcd(x,0()) -> x
 gcd(0(),s(y)) -> s(y)
 gcd(s(x),s(y)) -> gcd(mod(s(x),s(y)),mod(s(y),s(x)))
 lt(x,0()) -> false()
 lt(0(),s(x)) -> true()
 lt(s(x),s(y)) -> lt(x,y)
