Difficulty: Medium
About this MCQ
This Medium Data Structures question asks: The concept in which a method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree is best known as which of these terms? The correct choice is D. In-order traversal. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Data Structures items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Data Structures so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Data Structures item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. Self-referential structure
Why not A: “Self-referential structure” does not fit this question. The answer is In-order traversal.
- B. B-tree
Why not B: “B-tree” does not fit this question. The answer is In-order traversal.
- C. Adjacency list
Why not C: “Adjacency list” does not fit this question. The answer is In-order traversal.
- D. In-order traversal ✓
Correct answer
D. In-order traversal
Explanation
In-order traversal (option D) is the accepted answer to “The concept in which a method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree is best known as which of these terms”. Option A (Self-referential structure) does not fit this question. Option B (B-tree) does not fit this question. Option C (Adjacency list) does not fit this question. For this Data Structures question, the accepted answer is In-order traversal.
