This is the second of four videos about the bubble sort. The bubble sort, otherwise known as the ripple sort or the sinking sort is one of the simplest sorting algorithms and is therefore relatively easy to understand and implement. The bubble sort performs well for relatively small amounts of data, but struggles with very large amounts of data. This video describes pseudocode for a simple bubble sort, and for some enhancements. The videos that follow include VB.NET implementation code for a bubble sort.
