Consider the following statements:
(i) First-in-first out types of computations are efficiently supported by STACKS.
(ii) Implementing LISTS on linked lists is more efficient than implementing LISTS on an array for almost all the basic LIST operations.
(iii) Implementing QUEUES on a circular array is more efficient than implementing QUEUES, on a linear array with twg indices.
(iv) Last-in-first-out type of computations are efficiency supported by QUEUES.
  • a)
    (ii), (iii) are true
  • b)
    (i), (ii) are true
  • c)
    (iii), (iv) are true
  • d)
    (ii), (iv) are true
Correct answer is option 'A'. Can you explain this answer?

Stack is UFO system so FIFO not supported by stack hence option statement 1 is incorrect and queue is using FIFO so statement 4 is also wrong.

Efficiency of Data Structures

STACKS:

- First-in-first-out types of computations are not efficiently supported by STACKS because it is a Last-in-first-out (LIFO) data structure.
- Therefore, statement (i) is false.

LISTS:

- Implementing LISTS on linked lists is more efficient than implementing LISTS on an array because linked lists can dynamically allocate memory while arrays are fixed in size.
- For basic LIST operations like insertion and deletion, linked lists can perform better than arrays.
- Therefore, statement (ii) is true.

QUEUES:

- Implementing QUEUES on a circular array is more efficient than implementing QUEUES on a linear array with two indices because a circular array can reuse unused space in the array while a linear array cannot.
- Therefore, statement (iii) is true.
- Last-in-first-out type of computations are not efficiently supported by QUEUES because QUEUES are First-in-first-out (FIFO) data structures.
- Therefore, statement (iv) is false.

Conclusion:

- Statements (ii) and (iii) are true.
- Statements (i) and (iv) are false.
