What is tree traversal?

• A. The process of searching for a specific node in a tree
• B. The method of visiting all nodes in a tree data structure
• C. The insertion of nodes in a balanced manner
• D. The deletion of nodes in a tree

Answer: (B)

Tree traversal refers to the method of systematically visiting all the nodes in a tree data structure. This process allows for the efficient retrieval and processing of the data stored in the tree. There are several traversal techniques, including in-order, pre-order, post-order, and level-order traversals. Each of these methods serves specific purposes, such as implementing algorithms for searching, sorting, or displaying data stored in a tree. The focus of tree traversal is on ensuring every node is accessed in a particular order, which is essential for tasks such as evaluating expressions or generating sorted outputs. This approach helps understand the hierarchy and relationships between nodes within the tree structure, making it integral to working with trees in computer science.
