Selection sort

Selection sort is a sorting algorithm, often used in computer science. It operates by selecting the smallest (or largest) element from an unordered list, placing it at the beginning (or end) of the list, and then repeating the process for the remaining elements. As it progresses, it continuously sorts and builds the sorted list.

Selection sort works best on a randomly ordered list and has a time complexity of O(n2), making it slower than some other sorting algorithms. It is considered an “in-place” sorting algorithm in that it does not require extra space to sort an array.

Selection sort can be a suitable algorithm for certain types of programs, but it cannot be used for large data sets because it is very slow. Additionally, it is not very stable, which means it can potentially change the relative order of equal elements.

Selection sort is used in programming languages such as C, C++, Java, Python, and JavaScript, among others. It is also one of the fundamental sorting methods taught in introductory computer science courses.
