In-Order Traversal in Binary Search Trees
Explore how to implement in-order traversal in binary search trees using a recursive approach in Java. Understand the left-root-right visiting order and its application to print nodes in non-decreasing order. This lesson clarifies traversal steps, recursion base cases, and the overall time complexity of O(n).
We'll cover the following...
In-Order Traversal
In this type, the elements are traversed in a “left-root-right” order: we first visit the left node, then comes the turn of the root, and finally the right child. The following steps are required to perform In-Order Traversal, starting from the root node:
-
Traverse the left sub-tree of currentNode, recursively using the
InOrder()function. -
Visit the current node and read.
-
Traverse the right sub-tree of currentNode, recursively using the
In-Order()function. ...
