Hi, So this has happened before , and it happens from time to time , only this time I really got frustrated and hence am asking this question . . Why is my segment tree so slow?

Some problems like this -> 301D - Yaroslav and Divisors , have the official solution, the same as the solution that I code but somehow my segment tree is always very slow. This has happened before in live contests as well . Maybe my implementation is very bad , that's why I want to learn where I am making mistake , and please provide me with a better implementation if I am making a mistake..

My implementation to the above problem,using segment trees, which TLE's --> 36075338 . Help me out on this please!
