Delete Nodes And Return Forest Solved Medium Topics Companies Given the root of a binary tree, each node in the tree has a distinct value. After deleting all nodes with a value in to_delete, we are left with a forest (a disjoint union of trees). Return the roots of the trees in the remaining forest. You may return the result in any order. Example 1: Input: root = [1,2,3,4,5,6,7], to_delete = [3,5] Output: [[1,2,null,4],[6],[7]] Example 2: Input: root = [1,2,4,null,3], to_delete = [3] Output: [[1,2,4]] Constraints: The number of nodes in the given tree is at most 1000. Each node has a distinct value between 1 and 1000. to_delete.length = 1000 to_delete contains distinct values between 1 and 1000.
