The Java Advanced Data Structures and Algorithm Literacy (Beginner Level) benchmark measures your knowledge of the basic structure of a binary tree and utilizing tree traversal algorithms. You will be evaluated on your skills in implementing different types of graphs in code using common representations. The learners who score high on this benchmark demonstrate that they have the skills to work with binary trees and graph algorithms in Java.
