The difference with this data structure is you can have more than one key in the data structure (similar to multiset versus set). I'll show you how to use a few other functions like find, erase, and insert, as well as how to retrieve all of the keys using lower_bound, upper_bound, and a more efficient equal_range. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel! ►Join our free community: https://courses.mshah.io/communities/Q29tbXVuaXR5LTI3MzAz
