Write the recursive version of the function reduce which takes

• reducer - a two-argument function that reduces elements to a single value
• s - a sequence of values
• base - the starting value in the reduction. This is usually the identity of the reducer

If you're feeling stuck, think about the parameters of reduce.

from operator import add, mul

def reduce(reducer, s, base):
    """Reduce a sequence under a two-argument function starting from a base value.

    >>> def add(x, y):
    ...     return x + y
    >>> def mul(x, y):
    ...     return x*y
    >>> reduce(add, [1,2,3,4], 0)
    10
    >>> reduce(mul, [1,2,3,4], 0)
    0
    >>> reduce(mul, [1,2,3,4], 1)
    24
