2925. Maximum Score After Applying Operations on a Tree

Leetcode Solutions

Post-order DFS Traversal to Maximize Score

  1. Create a graph representation of the tree using the given edges.
  2. Define a recursive function get_min that performs a post-order DFS traversal.
  3. For each node, recursively call get_min on its children that are not the parent.
  4. If the node is a leaf, return its value as the minimum deductible value.
  5. Otherwise, calculate the sum of the minimum deductible values from its children.
  6. Determine the minimum deductible value for the current node by taking the minimum of its value and the sum from step 5.
  7. After the traversal, subtract the minimum deductible value at the root from the sum of all values to get the maximum score.
  8. Return the maximum score.
