Identify the correct definition of In-order traversal.
Difficulty: Medium
About this MCQ
This Medium Data Structures question asks: Identify the correct definition of In-order traversal. The correct choice is A. A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree.. 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. A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree. ✓
- B. A way of representing a graph where each vertex stores a list of its neighboring vertices.
Why not B: “A way of representing a graph where each vertex stores a list of its neighboring vertices.” does not fit this question. The answer is A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree..
- C. A situation in a hash table where two different keys produce the same hash value.
Why not C: “A situation in a hash table where two different keys produce the same hash value.” does not fit this question. The answer is A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree..
- D. A node structure that contains a pointer or reference to another node of the same type, forming the basis of linked structures.
Why not D: “A node structure that contains a pointer or reference to another node of the same type, forming the basis of linked structures.” does not fit this question. The answer is A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree..
Correct answer
A. A method of visiting all nodes of a tree by processing the left subtree, then the node, then the right subtree.
Explanation
A method of visiting all nodes of a tree by processing the left subtree then the node then the right subtree option A is the accepted answer to Identify the correct definition of In-order traversal Option B A way of representing a graph where each vertex stores a list of its neighboring vertices does not fit this question Option C A situation in a hash table where two different keys produce the same hash value does not fit this question Option D A node structure that contains a pointer or reference to another node of the same type forming the basis of linked structures does not fit this question For.
