Given a nested list of integers, return the sum of all integers in the list weighted by their depth.Each element was either an integer, or a list--whose elements may also be integers or other lists.Different from the previous question where weight are increasing from root to leaf, now the weight are defined from bottom u P. i.e., the leaf level integers has weight 1, and the root level integers has the largest weight.Example 1:Given the list [[1,1],2,
