Q1421: How does stepwise refinement impact the complexity of problem-solving?
- A: It reduces complexity by breaking down the problem into simpler, manageable parts
- B: It increases complexity by avoiding a structured approach
- C: It has no impact on complexity and treats the problem as a whole
- D: It eliminates the need for problem-solving altogether

A
Q1422: What role does intuition play when using stepwise refinement and top-down methodology?
- A: Intuition can guide the decomposition of the problem, making the structured approach more effective
- B: Intuition is irrelevant in the stepwise refinement process
- C: Intuition replaces the need for any structured methodology
- D: Intuition complicates the top-down approach without benefits

Q1424: In a sequential search algorithm, what indicates the end of the search?
- A: Reaching a target value or a name greater than the target
- B: Reaching the end of the list without finding the target
- C: Reaching a name less than the target
- D: Finding a name that matches the target

A
Q1425: When using a sequential search, what does reaching a name greater than the target indicate?
- A: The target value is not in the list
- B: The target value is in the list
- C: The list needs to be sorted
- D: The search needs to be restarted

A
Q1426: What does the pseudocode while (TargetValue > TestEntry and entries remain) represent in the sequential search algorithm?
- A: The condition to continue searching if the target value is greater than the current entry and entries remain
- B: The condition to end the search when the target value is found
- C: The condition to start the search from the beginning of the list
- D: The condition to sort the list before searching

A
Q1427: In the sequential search pseudocode, what happens if the target value equals the test entry?
- A: The search is declared a success
- B: The search continues with the next entry
- C: The search is declared a failure
- D: The search restarts from the beginning
View Answer
A
Q1428: What additional check is included in the pseudocode to handle an empty list?
- A: if (List is empty): Declare search a failure
- B: if (List is full): Declare search a success
- C: if (List contains duplicates): Ignore duplicates
- D: if (List is sorted): Continue searching
View Answer
A
Q1429: How does the pseudocode handle the case when the list is not empty?
- A: By proceeding with the search algorithm
- B: By declaring the search a failure
- C: By sorting the list first
- D: By restarting the search

Q1430: Which of the following best describes the sequential search algorithm’s approach?
- A: Scanning the list from the beginning to find a match or determine non-existence
- B: Using binary search to quickly find the target value
- C: Sorting the list before performing the search
- D: Jumping to specific list entries based on target value
