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.
