DS - intro

Which of the following best describes the fundamental purpose of a data structure?

• • To facilitate the graphical visualization of complex datasets.

• To organize and store data in computer memory for efficient use.

• • To compress data into smaller sizes, reducing storage requirements.

• • To secure data from unauthorized access and potential corruption.

How are data elements typically arranged within a linear data structure?

• In a sequential manner, where each element follows the next.

• • Based on their values, with larger values always preceding smaller values.

• • In a hierarchical fashion, with parent-child relationships.

• • Randomly, without any specific order or connection between elements.

Which option is an example of a non-linear data structure?

• stack

• linked list

• array

• tree

What is the primary role of Abstract Data Types (ADTs) in the design of data structures?

• • To dictate the exact memory allocation for a data structure.

• To provide an implementation-independent view of data and operations.

• • To specify implementation details like pointer arithmetic.

• • To directly manage the hardware-level interactions of data access.

Which operation is used to add an element to the top of a stack?

• Push

• • Insert

• • Enque

• • Pop

What is the characteristic principle by which a stack operates?

• • First-In, First-Out (FIFO)

• • Smallest Element First (SEF)

• Last-In, First-Out (LIFO)

• • Random Access Data Order (RADO)

In a queue data structure, which end is associated with the deletion of elements?

• • The middle of the queue.

• • Either end, depending on implementation.

• The front end of the queue.

• • The rear end of the queue.

What operation involves accessing each data element exactly once to process it?

• • Searching

• • Deletion

• Traversing

• • Insertion

Which characteristic ensures that each step of an algorithm has only one meaning, leading to a clear result?

• Unambiguousness

• • Effectiveness

• • Input

• • Finiteness

What is a crucial characteristic of an algorithm regarding its termination?

• It must terminate after a finite number of steps.

• • It must be able to run indefinitely without stopping.

• • It should depend solely on external user intervention to stop.

• • It should always produce multiple different outputs for the same input.
