Is there a function that receives a list x and returns a list y such that y[[i]] = intersect(x[[1]][[i]], x[[2]][[i]], ...) ?
Sorry for cross-posting this on the hadoop user mailing list and here, but this is getting an urgent matter for me.
In an application I am working on, a requirement is to do massive set intersection, to the tune of 10-1,000,000 items or so.The items that we are intersecting are simply ObjectId\'s.
Is there an algorithm that, given two sets, computes their int开发者_高级运维ersection in linear time?
I 开发者_Go百科haven\'t been able to find any satisfactory coverage of this topic all in one place, so I was wondering:
I sp开发者_开发技巧ent a considerable amount of time coding in Baeza-Yates\' fast set intersection algorithm for one of my apps. While I did marginally out-do the STL set_intersect, the fact that I re
assume that we have a data1 and data2. How can I intersect them with std::set_intersect()? struct pID {
