# Problem statement

For this challenge, you are given a nested list of integers. A nested list is a data structure in which each element is either an integer or a list whose elements may also be integers or other lists.


Your task is to implement a function that takes a nested list as input and returns the sum of each integer in the list multiplied by its depth. Here, an integer’s **depth** is the number of lists that it is nested inside of. For example, in the nested list `[1,[[3,[4]],2],1]`, each integer’s value is set to its depth.


## Input
The function’s input will be a list of nested integers. The following is an example of the input list:
