What is the time complexity of the inorder traversal of a binary tree?
Steps
Concepts
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 what inorder traversal means. Inorder traversal means visiting the left child, then the current node, and finally the right child.
Step 3: Realize that during inorder traversal, we visit each node in the tree exactly once.
Step 4: Count the total number of nodes in the tree, which we call 'n'.
Step 5: Since we visit each of the 'n' nodes once, the time taken for the traversal is proportional to 'n'.
Step 6: Conclude that the time complexity of the inorder traversal is O(n).
