Question
You will,
1. Pick a pivot using median of three
2. Then do insertion sort on the list
3. Then do recursive quick sort on the part less than the pivot. And recursive quick sort on the part greater than the pivot.
It's a really silly algorithm because the partition runtime is really bad.

And recursive quick sort on the part greater than the pivot. It's a really silly algorithm because the partition runtime is really bad.
Implement the most ridiculous quick sort algorithm in the world which uses an insertion sort to partition the values.
Your algorithm uses median of 3 to select a pivot. When it partitions based on the pivot, your algorithm does an
insertion sort on the values to determine the values less than the pivot and greater than the pivot partitions.
Solution requirements:
Use pseudocode as close to Java code (i.e. no English explanations)
• You will be given partial points based on how: pseudocode usage, understanding of the problem shown in
your code.
• Show how your algorithm would sort a small example of 15 numbers on paper. Partial credit will be given
based on the number of steps you show sorting the numbers.
