Day–Stout–Warren algorithm

The day–stout–warren algorithm is a type of computer program used to quickly organize data. It works by taking all of the data it is given and sorting it into different groups. It starts by picking one item (which we call the "pivot") and then moving all the items that are bigger than the pivot in one direction, and all the items that are smaller in the other direction. Then it takes the two groups and does the same thing again to each group, until all the items have been divided into separate groups. This way, the data will be in order from the smallest item to the biggest item. The day–stout–warren algorithm is a very efficient way of sorting data and is often used by computers to quickly sort big piles of data.
