WebJul 9, 2024 · You can find the GCD of the left and right subbarrays and compute the GCD of those two. This works because GCD of a list of numbers remains the same if you replace any number with its GCD w.r.t any of the subarrays containing that number. FYI there is a nice one-liner for this std::reduce (arr.begin (),arr.end (),arr [0],GCD);. Couple of points: WebAccording to the docs, the asymptotic running time of both HGCD and GCD is O (M (N)*log (N)), where M (N) is the time for multiplying two N-limb numbers.
