Leetcode Problem 2458. Height of Binary Tree After Subtree Removal Queries

2458. Height of Binary Tree After Subtree Removal Queries

Leetcode Solutions

DFS with Height Annotation and Query Processing

  1. Perform a DFS traversal starting from the root node.
  2. For each node, recursively find the maximum height of its left and right subtrees.
  3. Annotate each node with the maximum height reachable via its left and right children.
  4. Store the maximum height at each level of the tree during the DFS.
  5. After the DFS, process each query by checking if the subtree being removed affects the overall height of the tree.
  6. If the subtree being removed does not contain the tree's maximum height, the overall height remains the same.
  7. If the subtree being removed contains the maximum height, find the next maximum height from the annotated nodes.
  8. Return the results of all queries as an array.
