Solution: Delete Nodes And Return Forest
Explore how to delete nodes from a binary tree by traversing it with depth-first search. Understand the approach to splitting the tree into a forest of disjoint subtrees and implement an effective algorithm to return the roots of the remaining trees.

Statement
Given the root of a binary tree where each node has a unique value, your task is to delete all nodes with values specified in the deleteNodes array. After performing the deletions, the tree will split into a forest—a collection of disjoint trees. Return the roots of the remaining trees in the forest in any order.
