If you are using c++, then you can use gnu pbds. It makes things really easy.
Yeah I just read a blog related to that, it is really great. But can we do without it?
I don't know, but if the constraints are less like x, p <= 10^6 then we can use BIT. May be we can apply here using some compression technique.
there's an Editorial for CSES Range Queries section . you can also refer to my comment if you want to solve it using bit .
