  /**
   * The `mapAccumRight` function behaves like a combination of map and reduce; it
   * applies a function to each element of a list, passing an accumulating
   * parameter from right to left, and returning a final value of this
   * accumulator together with the new list.
   *
   * Similar to [`mapAccum`](#mapAccum), except moves through the input list from
   * the right to the left.
   *
   * The iterator function receives two arguments, *acc* and *value*, and should
   * return a tuple *[acc, value]*.
   *
   * @func
   * @memberOf R
   * @since v0.10.0
   * @category List
   * @sig ((acc, x) -> (acc, y)) -> acc -> [x] -> (acc, [y])
   * @param {Function} fn The function to be called on every element of the input `list`.
   * @param {*} acc The accumulator value.
   * @param {Array} list The list to iterate over.
   * @return {*} The final, accumulated value.
   * @see R.addIndex, R.mapAccum
   * @example
   *
   *      const digits = ['1', '2', '3', '4'];
   *      const appender = (a, b) => [b + a, b + a];
   *
   *      R.mapAccumRight(appender, 5, digits); //=> ['12345', ['12345', '2345', '345', '45']]
   * @symb R.mapAccumRight(f, a, [b, c, d]) = [
   *   f(f(f(a, d)[0], c)[0], b)[0],
   *   [
   *     f(a, d)[1],
   *     f(f(a, d)[0], c)[1],
   *     f(f(f(a, d)[0], c)[0], b)[1]
   *   ]
