WebNov 5, 2024 · An in-order traversal of a binary search tree causes all the nodes to be visited in ascending order of their key values. If you want to create a list of the data in a binary tree sorted by their keys, this is one way to do it. The simplest way to carry out a traversal is the use of recursion (discussed in Chapter 6).
