You are given a nested list of integers nestedList. Each element is either an integer or a list whose elements may also be integers or other lists.
The depth of an integer is the number of lists that it is inside of. For example, the nested list [1,[2,2],[3],2],1] has each integer's value set to its depth.
Return the sum of each integer in nestedList multiplied by its depth.
Example 1:
Input: nestedList = [[1,1],2,[1,1]]
Output: 10
Explanation: Four 1's at depth 2, one 2 at depth 1.
1×2 + 1×2 + 2×1 + 1×2 + 1×2 = 10.
Example 2:
Input: nestedList = [1,[4,[6]]]
Output: 27
Explanation: One 1 at depth 1, one 4 at depth 2, and one 6 at depth 3.
1×1 + 4×2 + 6×3 = 27.
Example 3:
Input: nestedList = [0]
Output: 0
Constraints:
- 1 <= nestedList.length <= 50
- The values of the integers in the nested list is in the range [-100, 100].
- The maximum depth of any integer is less than or equal to 50.
