For instance, sorting is a common technique used inevitably in many programs which would like to sort a list of data items in either ascending or descending order. Also, linked lists and stacks and similar data structures are of outmost importance and is necessary to cover them out since they are used quite often. Such data structures are very useful utilities which enlighten your programming skills. These will be covered for you in as general application as possible, so that you may use them in any of your programs and practice them for your applications.
Feel free to go through the following articles and try them yourself and manipulate them in your own way.
