Use Bubble Sort to sort the list:
7, 12, 5, 22, 13, 32
What is the maximum number of comparisons required for a list of 6 numbers?
How many vcomparisons did I actually need?

Number of comparisons for 6 numbers:
5+4+3+2+1=15
You need all 15 comparisons unless you modify the algorithm to keep track of exchanges.
There are 4 exchanges in this particular example. 
Thanks for explaining this to me!

You're welcome!
