Question 1 of 10

1. Question
Which description best describes a bubble sort algorithm?
- The data set is repeatedly halved until each item is separated, then each pair of data is ordered, then each pair of pairs is ordered etc, until the data set is recombined in a sorted manner.
- The algorithm repeatedly steps through a data set, comparing each pair in the data set, swapping them if they are in the wrong order.
- The algorithm steps through the data set and the data items are re-positioned into a new ordered list, one item at a time.
- The data set is repeatedly stepped through and on each pass, the smallest item is swapped with the left most unsorted item, until the entire data set is in order.

Question 2 of 10

2. Question
What is a PASS when discussing a bubble sort?
- It is the swapping of two numbers to get them ordered.
- It is when two numbers are not swapped (left in the same order) as they are already in order.
- It is the term used to describe one complete sweep of the data set.
- It is the term used to describe the situation when no items are reordered in a data set (as they are already ordered).
