Difficulty: Hard
About this MCQ
This Hard Data Structures question asks: What is Trie primarily used for? The correct choice is A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.. 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 tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching. ✓
- B. A linked list in which the last node points back to the first node, forming a loop.
Why not B: “A linked list in which the last node points back to the first node, forming a loop.” does not fit this question. The answer is A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching..
- C. A linked list where each node has pointers to both the next and previous nodes.
Why not C: “A linked list where each node has pointers to both the next and previous nodes.” does not fit this question. The answer is A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching..
- D. A binary tree in which each node's left subtree contains smaller values and right subtree contains larger values.
Why not D: “A binary tree in which each node's left subtree contains smaller values and right subtree contains larger values.” does not fit this question. The answer is A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching..
Correct answer
A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.
Explanation
A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching is the value that answers What is Trie primarily used for option A Option B A linked list in which the last node points back to the first node forming a loop does not fit this question Option C A linked list where each node has pointers to both the next and previous nodes does not fit this question Option D A binary tree in which each node's left subtree contains smaller values and right subtree contains larger values does not fit this question For this Data Structures question the accepted answer is A tree-like.
