About this MCQ

This Hard Data Structures MCQ checks one syllabus fact.

The question is: “What is Trie primarily used for?”

The accepted answer is A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.. A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching is the fact required by 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 match the stem it is a near-miss used to catch incomplete recall of A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching Option C A linked list where each node has pointers to both the next and previous nodes does not match the stem it is a near-miss used to catch incomplete recall of A tree-like data structure used to efficiently store and retrieve strings.

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.” is not correct. The accepted answer is A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.. A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching is the fact required by What is Trie primarily used for option A Option B A
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.” is not correct. The accepted answer is A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.. A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching is the fact required by What is Trie primarily used for option A Option B A
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.” is not correct. The accepted answer is A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.. A tree-like data structure used to efficiently store and retrieve strings especially for prefix matching is the fact required by What is Trie primarily used for option A Option B A

Correct answer

A. A tree-like data structure used to efficiently store and retrieve strings, especially for prefix matching.
