Try these first

1. 1.

   What does stability mean in sorting?

   Hint

2. 2.

   Name one stable sorting algorithm.

   Hint

   Consider algorithms that keep original order intact.

3. 3.

   Which of the following is a feature of stable sorting algorithms?

   • They are always the fastest
   • They retain the relative order of equal elements
   • They require more memory

   Hint

   Think about what stability means in sorting.

4. 4.

   True or False: Quick sort is exclusive to stable sorting.

   • True
   • False

   Hint

   Consider how quick sort operates during sorting.

5. 5.

   Imagine you are tasked with sorting a list of employees by salary and then by last name. Discuss the implications if you used a non-stable sort like quick sort.

   Hint

   Consider how the order is managed in multi-key sorting scenarios.

6. 6.

   Critically analyze a scenario in a database where the choice of sorting algorithm impacts data retrieval accuracy.

   Hint

   Think about how data is reported and the importance of maintaining the original data order.
