+/**
+ * 339. Nested List Weight Sum
+ *
+ * Given a nested list of integers, return the sum of all integers in the list weighted by their depth.
+ * Each element is either an integer, or a list -- whose elements may also be integers or other lists.
+ *
+ * Example 1:
+ * Input: [[1,1],2,[1,1]]
+ * Output: 10
+ * Explanation: Four 1's at depth 2, one 2 at depth 1.
+ *
+ * Example 2:
+ * Input: [1,[4,[6]]]
+ * Output: 27
+ * Explanation: One 1 at depth 1, one 4 at depth 2, and one 6 at depth 3; 1 + 4*2 + 6*3 = 27.
