Set::begin and set::end in C++ STL

Set is a data structure that stores elements. It is a simple yet effective data structure when used correctly. In C++'s Standard Template library (STL), we have set as a container that is used to store the values which are unique i.e no value in a set can be repeated or edited. If you want to edit the value added by you the only way is to remove the wrong element and add the correct one.
