Question 2.
Why is quicksort generally considered fast?
Show hintHide hint
Consider how many elements it divides at each step.
3Question 3.
What is the main benefit of stable sorting?
- It is faster than all algorithms

Question 5.
Consider a dataset of 500,000 records that needs to be sorted primarily by date and secondarily by name. Which sorting algorithm would you choose and why?
Show hintHide hint
Think about both the size and nature of the data.
Question 6.
You have two algorithms: Algorithm A (O(n^2)) and Algorithm B (O(n log n)). If you need to sort 1000 records which would you choose? Explain your reasoning.
