Solution: Nested List Weight Sum II
Understand how to solve the Nested List Weight Sum II problem by using depth-first search to find max depth and compute weighted sums of integers in nested lists. This lesson guides you through the recursive approach needed to traverse and aggregate values based on their depth, enhancing your grasp of tree traversal and algorithmic problem-solving.
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.
Constraints:
