Leetcode Problem 2049. Count Nodes With the Highest Score
Leetcode Solutions
DFS Traversal to Calculate Subtree Sizes and Scores
- Build an adjacency list to represent the tree structure from the
parentsarray. - Define a recursive DFS function that calculates the size of each subtree.
- During the DFS traversal, calculate the score for each node by multiplying the sizes of the left subtree, right subtree, and the remaining nodes in the tree.
- Keep track of the maximum score encountered and the count of nodes with that score.
- After the DFS traversal is complete, return the count of nodes with the maximum score.
