# Sorting out the sorting algorithms

We have chosen three unnamed sorting algorithms to sort various sets of data. Click on each histogram
below to see a sorting algorithm in action. Figure out what sorting algorithm is acting on each histogram.

## Random data

**#1** **#2** **#3**

## An initially presorted array

**#1** **#2** **#3**

## An initially reverse-sorted array

**#1** **#2** **#3**
