Sorting is one of the most used algorithms in computer programming. Even in our everyday life, if things are not sorted, we can have a hard time with them. Sorting can pave the way for faster searching or ordering of items in a collection. Sorting can be done in many different ways, such as in ascending order or descending order. Sorting can also be based on the type of data. For example, sorting a collection of names will require lexicographical sorting rather than numerical sorting. As sorting can play an important role for other data structures and their efficiencies, there are many different sorting algorithms available. We will explore a few of the most popular sorting algorithms in this chapter, along with their complexity and usages.
