The algorithms in this book represent a body of knowledge developed over the last 50 years that has become indispensible in the efficient use of the computer. In this lecture we discuss selection sort, which is one of the simplest algorithms. So, the algorithm starts by picking a single item which is called pivot and moving all smaller items before it, while all greater elements in the later portion of the list. You may or may not have seen these algorithms presented earlier, and if you have they may have been given in a slightly different form. Sorting is a technique to rearrange the elements of a list in ascending or descending order, which can be numerical, lexicographical, or any userdefined order.

Selection sort is very easy to analyze since none of the loops depend on the data in the array. Then finds the second smallest element and exchanges it with the element in the second position and continues until the entire array is sorted. Sorting is nothing but arranging the data in ascending or descending order.
