### What is a Sorting Algorithm?

Sorting refers to arranging data in a particular format. Sorting algorithm specifies the way to arrange data in a particular order. Most common orders are in numerical or lexicographical order. The importance of sorting lies in the fact that data searching can be optimized to a very high level, if data is stored in a sorted manner. Sorting is also used to represent data in more readable formats. Sorting algorithms may require some extra space for comparison and temporary storage of few data elements.

A computer program is a collection of instructions to perform a specific task. For this, a computer program may need to store data, retrieve data, and perform computations on the data. A data structure is a named location that can be used to store and organize data. And, an algorithm is a collection of steps to solve a particular problem. Learning data structures and algorithms allow us to write efficient and optimized computer programs. Programiz offers a complete series of easy to follow DSA tutorials along with suitable examples.

Sorting algorithms are a set of instructions that take an array or list as an input and arrange the items into a particular order. Sorts are most commonly in numerical or a form of alphabetical called lexicographical order, and can be in ascending A-Z, or descending Z-A, order. Since sorting can often reduce the complexity of a problem, it is an important algorithm in Computer Science. These algorithms have direct applications in searching algorithms, database algorithms, divide and conquer methods, data structure algorithms, and many more. When using different algorithms some questions have to be asked. How big is the collection being sorted?

Sorting is nothing but arranging the data in ascending or descending order. The term sorting came into picture, as humans realised the importance of searching quickly. There are so many things in our real life that we need to search for, like a particular record in database, roll numbers in merit list, a particular telephone number in telephone directory, a particular page in a book etc. All this would have been a mess if the data was kept unordered and unsorted, but fortunately the concept of sorting came into existence, making it easier for everyone to arrange data in an order, hence making it easier to search. If you ask me, how will I arrange a deck of shuffled cards in order, I would say, I will start by checking every card, and making the deck as I move on. Since the beginning of the programming age, computer scientists have been working on solving the problem of sorting by coming up with various different algorithms to sort data. There are many different techniques available for sorting, differentiated by their efficiency and space requirements.

In computer science, a binary search tree is an ordered data structure that is logically visualized as a tree with a single root node and has two children, one on its right side and the other on its left. These are known as the left child and right child. These children further make subtrees until they reach leaf nodes.

The specific sorting algorithm is not mandated by the language standard and may vary across implementations, but the worst-case asymptotic complexity of the function is specified: a call to sort must perform O N log N comparisons when applied to a range of N elements. Here, RandomAccessIterator is a templated type that must be a random access iterator , and first and last must define a sequence of values, i. The third argument, also of a templated type, denotes a comparison predicate. This comparison predicate must define a strict weak ordering on the elements of the sequence to be sorted. This code sample sorts a given array of integers in ascending order and prints it out.

Когда Сьюзан вернулась в Третий узел, Грег Хейл как ни в чем не бывало тихо сидел за своим терминалом. ГЛАВА 30 Альфонсо XIII оказался небольшим четырехзвездочным отелем, расположенным в некотором отдалении от Пуэрта-де-Хереса и окруженным кованой чугунной оградой и кустами сирени. Поднявшись по мраморным ступенькам, Дэвид подошел к двери, и она точно по волшебству открылась. Привратник проводил его в фойе. - Багаж, сеньор.

#### Why Sorting Algorithms are Important

Еще через четыре месяца Энсей Танкадо приступил к работе в Отделении криптографии Агентства национальной безопасности США. Несмотря на солидный заработок, Танкадо ездил на службу на стареньком мопеде и обедал в одиночестве за своим рабочим столом, вместо того чтобы вместе с сослуживцами поглощать котлеты из телятины и луковый суп с картофелем - фирменные блюда местной столовой. Энсей пользовался всеобщим уважением, работал творчески, с блеском, что дано немногим. Он был добрым и честным, выдержанным и безукоризненным в общении. Самым главным для него была моральная чистота. Именно по этой причине увольнение из АН Б и последующая депортация стали для него таким шоком. Танкадо, как и остальные сотрудники шифровалки, работал над проектом ТРАНСТЕКСТА, будучи уверенным, что в случае успеха эта машина будет использоваться для расшифровки электронной почты только с санкции министерства юстиции.

Бринкерхофф опустился на стул, слушая, как стук ее каблуков затихает в конце коридора. По крайней мере Мидж не станет болтать. У нее есть и свои слабости. Она ведь и сама кое-что себе позволяла: время от времени они массировали друг другу спину. Мысли его вернулись к Кармен. Перед глазами возникло ее гибкое тело, темные загорелые бедра, приемник, который она включала на всю громкость, слушая томную карибскую музыку.

The emphasis here is on the analysis techniques, not the algorithms themselves; in particular the presentations here don't prioritise elements that would improve.
