Tree and Graph Data Structures

Learn the implementation details of tree and graph data structures, interview questions involving them, and the algorithms to solve them. This course builds on Bianca’s Practical Algorithms and Data Structures for Interviews courses. Unlike arrays, trees and graphs are non-linear. This allows for modeling things such as recommendation algorithms and social networks.
