This is a powerful algorithm that allows us to get the benefits of accumulate (i.e. fold) but also provide an execution policy for potential parallelism. Two 'gotcha's' remain 1. make s sure the initial type matches your result (as this is determined at compile-time by the template parameter type) 2. Make sure the default value for the constructed type is what you want it, if you choose the overload that omits 'init'. I'll show in this example how to think about 'parallel fold' operations. ►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
