/**
 * Returns a single item by iterating through the list, successively calling
 * the iterator function and passing it an accumulator value and the current
 * value from the array, and then passing the result to the next call.
 *
 * Similar to [`reduce`](#reduce), except moves through the input list from the
 * right to the left.
 *
 * The iterator function receives two values: *(value, acc)*, while the arguments'
 * order of `reduce`'s iterator function is *(acc, value)*.
 *
 * Note: `R.reduceRight` does not skip deleted or unassigned indices (sparse
 * arrays), unlike the native `Array.prototype.reduceRight` method. For more details
 * on this behavior, see:
 * https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduceRight#Description

 * @func
 * @memberOf R
 * @since v0.1.0
 * @category List
 * @sig ((a, b) -> b) -> b -> [a] -> b
 * @param {Function} fn The iterator function. Receives two values, the current element from the array
 *        and the accumulator.
 * @param {*} acc The accumulator value.
 * @param {Array} list The list to iterate over.
 * @return {*} The final, accumulated value.
 * @see R.reduce, R.addIndex
 * @example
 *
 *      R.reduceRight(R.subtract, 0, [1, 2, 3, 4]) // => (1 - (2 - (3 - (4 - 0)))) = -2
 *      //    -               -2
 *      //   / \              / \
 *      //  1   -            1   3
 *      //     / \              / \
 *      //    2   -     ==>    2  -1
 *      //       / \              / \
 *      //      3   -            3   4
 *      //         / \              / \
 *      //        4   0            4   0
