Consider the following statements:i. First-in-first-out types of compu...
Let's analyze each statement to determine which ones are true:
i. First-in-first-out types of computations are efficiently supported by STACKS.
- This statement is false. Stacks support Last-in-First-out (LIFO) operations, not FIFO. So, this statement is not true.
ii. Implementing LISTS on linked lists is more efficient than implementing LISTS on an array for almost all the basic LIST operations.**
- This statement is generally true. Linked lists allow for efficient insertion and deletion operations, which are costly in arrays due to the need to shift elements.
iii. Implementing QUEUES on a circular array is more efficient than implementing QUEUES on a linear array with two indices.
- This statement is true. Circular arrays can utilize the entire array space more efficiently and avoid unnecessary shifts compared to a linear array with two indices.
iv. Last-in-first-out type of computations are efficiently supported by QUEUES.
- This statement is false. Last-in-first-out (LIFO) operations are supported by stacks, not queues. Queues support First-in-First-out (FIFO) operations.
Conclusion
Based on the analysis:
- Statement ii and iii are true:
- 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 two indices.
Therefore, the correct answer is:
1. (ii) and (iii) are true
