15.1.7. Conclusion

Try these first

1. 1.

   What does the Quicksort algorithm aim to improve compared to merge sort?

   Hint

   Think about space complexity.

2. 2.

   Define what a pivot is in the context of Quicksort.

   Hint

   It serves as a benchmark for dividing the array.

3. 3.

   What is the main advantage of Quicksort over merge sort?

   • Requires more space
   • Is always faster
   • Sorts in-place

   Hint

   Consider memory efficiency.

4. 4.

   True or False: The pivot in Quicksort must always be the median.

   • True
   • False

   Hint

   Think about the flexibility in pivot selection.

5. 5.

   Design a scenario where Quicksort performs best, detailing your pivot choice and the expected efficiency.

   Hint

   Consider how balanced partitions lead to quicker sorting.

6. 6.

   Explain how variations of pivot selection might improve worst-case performance with examples.

   Hint

   Discuss how randomness plays a role in average-case performance.
