Solution: Nested List Weight Sum II
Explore how to apply depth-first search to compute the weighted sum of integers in nested lists by calculating maximum depth and weighting elements accordingly. This lesson helps you understand recursive traversal in trees and nested structures to solve complex coding interview problems efficiently.
We'll cover the following...
Statement
Given a nested list of integers, nestedList, where each element can either be an integer or a list, which can contain integers or more lists, return the sum of each integer in nestedList multiplied by its weight.
The weight of an integer is calculated as maxDepth minus the depth of the integer plus one.
The depth of an integer is defined as the number of nested lists it is contained within. For instance, the value of each integer in the list [1,[2,2],[[3],2],1] is equal to its depth. Let maxDepth represent the maximum depth of any integer in the nestedList.
