Define a procedure arithmeticIf(v, a, b, c) that returns a if v is greater than 0, b if v is equal to 0, and c if it is less than 0. Your function should have type (num, *, *, *) -> *, where, by * we mean that it could be any type.

def arithmeticIf(v, a, b, c):
    if v > 0:
        return a
    elif x == 0:
        return b
    else:
        return c
