This is a powerful algorithm also known as 'fold' for summing up, or otherwise performing a 'fold' operation using some binary operation. One gotcha is to make s sure the initial type matches your result (as this is determined at compile-time by the template parameter type). I'll show in this example how to think about 'fold' operations, and shortly we will talk about a related operation known as 'reduce'. ►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
