# Quiz: Data Structures Mock Tests on Tree Traversals.

## Quiz: Data Structures Mock Tests on Tree Traversals. All about the basic of Data Structures Tree Traversals . In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, Data Structure & Algorithms - Tree Traversal. Advertisements. Traversal is a process to visit all the nodes of a tree and may print their values too. Because, all nodes are connected via edges (links) we always start from the root (head) node
