Parameters
----------
f : callable[any, any]
The function to reduce the sequence with.
The first argument will be the element of the sequence; the second
argument will be the accumulator.
seq : iterable[any]
The sequence to reduce.
default : any, optional
The starting value to reduce with. If not provided, the sequence
cannot be empty, and the last value of the sequence will be used.
Returns
-------
folded : any
The folded value.
Notes
-----
This functions works by reducing the list in a right associative way.
For example, imagine we are folding with ``operator.add`` or ``+``:
.. code-block:: python
foldr(add, seq) -> seq[0] + (seq[1] + (seq[2] + (...seq[-1], default)))
In the more general case with an arbitrary function, ``foldr`` will expand
like so:
.. code-block:: python
foldr(f, seq) -> f(seq[0], f(seq[1], f(seq[2], ...f(seq[-1], default))))
For a more in depth discussion of left and right folds, see:
`https://en.wikipedia.org/wiki/Fold_(higher-order_function)`_
The images in that page are very good for showing the differences between
``foldr`` and ``foldl`` (``reduce``).
.. note::
For performance reasons is is best to pass a strict (non-lazy) sequence,
for example, a list.
