Question: In a binary tree, what is the time complexity of traversing all nodes using in-order traversal?

Options:

Correct Answer: O(n)

Solution:

In-order traversal visits each node exactly once, resulting in a time complexity of O(n).

In a binary tree, what is the time complexity of traversing all nodes using in-order traversal?

In a binary tree, what is the time complexity of traversing all nodes using in-order traversal?

Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children.
Step 2: Learn about in-order traversal. In in-order traversal, you visit the left child, then the current node, and finally the right child.
Step 3: Realize that during in-order traversal, you will visit each node in the tree exactly once.
Step 4: Count the total number of nodes in the binary tree. Let's say there are 'n' nodes.
Step 5: Since you visit each of the 'n' nodes once, the time taken to traverse the entire tree is proportional to 'n'.
Step 6: Conclude that the time complexity of in-order traversal is O(n).
