Question

what is trees and types of trees​

Answer 1

Answer:

Trees are abstract data structures, used to manage data in a hierarchical way, making data retrieving much more efficient than other data structure methods. A tree is a collection of nodes that are linearly connected and don't have any cyclic relations as shown in Figure 1. These nodes contain information and are usually arranged in a key-value structure. The key serves as an identifier for the data, and value is the actual data that you want to store.

Answer 2

Answer:

There are two main types of trees: deciduous and evergreen. Deciduous trees lose all of their leaves for part of the year.
