Leetcode Solutions

Depth-First Search (DFS) to Sum Values with Even-Valued Grandparent

  1. Define a helper function dfs that takes a node and its parent and grandparent values.
  2. If the current node is null, return 0.
  3. Calculate the sum for the current node's children by recursively calling dfs with updated parent and grandparent values.
  4. If the grandparent's value is even, include the current node's value in the sum.
  5. Return the sum of the current node's value (if applicable) and the values from its children.
