How Phantom Code Helps
Get real-time assistance for Height of Binary Tree After Subtree Removal Queries problems during coding interviews. Phantom Code provides instant solutions and explanations.
Examples
# Example 1
Input
root = [1,3,4,2,null,6,5,null,null,null,null,null,7], queries = [4]
Output
[2]
# Example 2
Input
root = [5,8,9,2,1,3,7,4,6], queries = [3,2,4,8]
Output
[3,2,3,2]
Constraints
The number of nodes in the tree is n.
2 <= n <= 105
1 <= Node.val <= n
All the values in the tree are unique.
m == queries.length
1 <= m <= min(n, 104)
1 <= queries[i] <= n
queries[i] != root.val
