Pruning is one of the most important cultural practices for maintaining woody plants, including ornamental trees and shrubs, fruits and nuts. Proper pruning requires a basic understanding of how plants respond to various pruning cuts. The principles and guidelines in this publication will help you master common pruning techniques.At the initial steps of pruning, the algorithm tends to cut off large sub-branches with many leaf nodes very quickly. Then pruning becomes slower and slower as the tree becoming smaller. The algorithm tends to cut off fewer nodes. Let's look at an example. Digital Recognition Example \(T_1\) is the smallest optimal subtree for \(\alpha_1 = 0\).Always wait to trim until the rains of winter are done, since pruning opens entry points for water-borne disease to enter the tree.

Given the root of a binary tree, return the same tree where every subtree (of the given tree) not containing a 1 has been removed.
