Data Structures 300 Unique MCQs

The defining property is that each node stores two links.
The other statements describe different structures or concepts.

Dynamic Array is a resizable array that grows when its capacity is exceeded.
This description distinguishes it from the other choices.

Dynamic Array is commonly used for maintaining an indexed sequence whose size changes.
Its design supports this task efficiently or naturally.

The defining property is that resizing may require allocating a larger block and copying elements.
The other statements describe different structures or concepts.

Dynamic Array fits because it supports maintaining an indexed sequence whose size changes and resizing may require allocating a larger block and copying elements.
Both clues point to this choice.

Singly Linked List is a sequence of nodes where each node points to the next node.
This description distinguishes it from the other choices.

Singly Linked List is commonly used for frequent insertions at the head.
Its design supports this task efficiently or naturally.

The defining property is that forward traversal is supported but direct backward traversal is not.
The other statements describe different structures or concepts.

Array is a contiguous collection of elements accessed by index.
This description distinguishes it from the other choices.

Array is commonly used for fast random access when the index is known.
Its design supports this task efficiently or naturally.

The defining property is that elements are typically stored in adjacent memory locations.
The other statements describe different structures or concepts.

Array fits because it supports fast random access when the index is known and elements are typically stored in adjacent memory locations.
Both clues point to this choice.
