2322. Minimum Score After Removals on a Tree

Leetcode Solutions

Iterate Over All Edge Pairs

  1. Create a graph representation of the tree using adjacency lists.
  2. Perform a depth-first search (DFS) to calculate the XOR of all nodes in the subtree rooted at each node.
  3. Iterate over all pairs of edges to be removed.
  4. For each pair, determine the three components formed by the removal.
  5. Calculate the XOR values for each of the three components.
  6. Calculate the score for the pair as the difference between the largest and smallest XOR values.
  7. Keep track of the minimum score encountered.
  8. Return the minimum score after considering all pairs.
