Data Structures 300 Unique MCQs

Circular Linked List fits because it supports round-robin scheduling and traversal can continue cyclically without reaching a null link.
Both clues point to this choice.

Stack is a linear structure that follows Last In, First Out order.
This description distinguishes it from the other choices.

Stack is commonly used for function-call management and undo operations.
Its design supports this task efficiently or naturally.

The defining property is that push and pop occur at the same end.
The other statements describe different structures or concepts.

Stack fits because it supports function-call management and undo operations and push and pop occur at the same end.
Both clues point to this choice.

Queue is a linear structure that follows First In, First Out order.
This description distinguishes it from the other choices.

Doubly Linked List fits because it supports efficient insertion or deletion when a node reference is available and each node stores two links.
Both clues point to this choice.

Circular Linked List is a linked list whose last node points back to the first node.
This description distinguishes it from the other choices.

Circular Linked List is commonly used for round-robin scheduling.
Its design supports this task efficiently or naturally.

Singly Linked List fits because it supports frequent insertions at the head and forward traversal is supported but direct backward traversal is not.
Both clues point to this choice.

Doubly Linked List is a sequence of nodes with links to both the next and previous nodes.
This description distinguishes it from the other choices.

Doubly Linked List is commonly used for efficient insertion or deletion when a node reference is available.
Its design supports this task efficiently or naturally.
