Today we teach the ability to perform range queries in $$$\mathcal{O}(1)$$$, regardless of the query rekwaired.

Consider $$$Q = [l, r]$$$.

Iterate over all quadraubles $$$\left(a,b,c,d\right)$$$, add $$$Q[a]\times Q[b]\times Q[c] - Q[d]^2$$$

Now to solve single qwery, output $$$\text{Quadruble}[l][r^2][r-l^r][l+r^l]$$$.

The precomputation took $$$\mathcal{O}(1)$$$ time because $$$a,b,c,d\le 10^{18}$$$, a constant

You solve every query in $$$\mathcal{O}(1)$$$ cuz u immediately output the formula.

if you dont trust me, try it in this problem

you can see that my code is fastest ($$$0.00$$$ s)

the usaco camp has ended actually i have this secret informations from the one and only Benq

actually the ones who will be in internation l olympiads of intormatica who will represant the united statat of amrika are

1- nor 2- Geothermal 3- xzm2024 4- awoo 5- Seryi 6- FerjaniSassi

they have officully qualified to the oio (olympiad international of intormatics), and they will participate offically

lets congratulate zem and wish good result!!

so it seems like many people are struggling to be red

I THINK THIS because you cant even write code

learn from the true red, this is how we write code https://codeforces.com/contest/4/submission/203467882

also people like Um_nik cant even be 1st because like they dont even know wavelet tree??? like it is so easy just make a tree

also a lot of people struggle to get to YELLOW which is the easiest rate to achieve,, because they write recursive segmant tree?? honestly go learn how to code...
