Solution: Delete Nodes And Return Forest
Explore the process of deleting specified nodes from a binary tree and producing a forest of remaining trees. Learn to implement a depth-first search algorithm that handles node removals, manages child nodes becoming new roots, and efficiently returns all forest roots after deletions. Understand time and space complexity considerations for this tree manipulation task.

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.
