An intro to Algorithms: Searching and Sorting algorithms
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? How much memory is at disposal to be used?
Back To Lectures Notes This lecture covers Chapter 12 of our textbook and part of the contents are derived from Wikipedia. Click here for the slides presentations. A sorting algorithm is an algorithm that puts elements of a list in a certain order. The most-used orders are numerical order and lexicographical order. Sorting algorithms provide an introduction to a variety of core algorithm concepts, such as big O notation, divide and conquer algorithms, data structures, best-, worst- and average-case analysis, time-space tradeoffs, and lower bounds. Classification : Computational complexity worst, average and best behavior of element comparisons in terms of the size of the list n. For typical sorting algorithms, a good behavior is O n log n and a bad behavior is O n 2.

These notes will look at. Sorting and searching: algorithms and lower bound. This class has two major thrusts which complement each other nicely: increasing the mathematical sophistication proofs and logic and introducing the mathematical foundation of computer science. Algorithms are the procedures a software program uses to manipulate the data in these structures. Do you know let us c pdf and solutions book, this is a very helpful book for learning c language?
Bubble sort is a simple sorting algorithm. This sorting algorithm is comparison-based algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in order. We take an unsorted array for our example. In this case, value 33 is greater than 14, so it is already in sorted locations. Next, we compare 33 with We swap these values. We find that we have reached the end of the array.
C++'s STL provides algorithm functions binary_search, lower_bound and upper_bound. • Java offers a set of overloaded binarySearch() static.

Bubble sort , sometimes referred to as sinking sort , is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort , is named for the way smaller or larger elements "bubble" to the top of the list.
