For example, if one algorithm requires 100 swaps, and another requires 50 swaps 1002, then we say that these two algorithms require the same. If you are expecting any issue and have something to do with the exception, catching it before you dispose the instance you are using and as other comments answers state. Selection sort also known as in place comparison sort is a simple sort that works by selecting one element and comparing it with the every next element and then swaping it as required. Various types and forms of sorting methods have been explored in this tutorial. There are various heuristic techniques which can be used to speed up sequential search algorithms.

External sorting is a term for a class of sorting algorithms that can handle massive amounts of data. 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. 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.
