+ * @function multiplicativePersistence

+ *   multiply the digits of a number until you reach a single digit.
+ *   For example, 39: 3×9=27, 2×7=14, 1×4=4 — persistence is 3.
+ * @param {number} n - A non-negative integer
+ * @returns {number} - The multiplicative persistence of n
+ * @see https://en.wikipedia.org/wiki/Persistence_of_a_number
+ * @example multiplicativePersistence(39) => 3
+ * @example multiplicativePersistence(999) => 4
+ * @example multiplicativePersistence(4) => 0
