364. Nested List Weight Sum II

Leetcode Solutions

Single Pass Depth-First Search (DFS)

  1. Define a helper function dfs that takes a nestedList, the current depth, and updates sumOfElements, sumOfProducts, and maxDepth.
  2. If the current NestedInteger is an integer, add its value to sumOfElements and its product with depth to sumOfProducts.
  3. If the current NestedInteger is a list, recursively call dfs on each element in the list with depth + 1.
  4. After the DFS traversal, calculate the final sum using the formula (maxDepth + 1) * sumOfElements - sumOfProducts.
  5. Return the final sum.
