Question about problem 233 — B. Non-square Equation

Правка en1, от Bekh, 2019-06-09 06:13:48

Hello,

I was wondering why in submissions like this 12604154 it is sufficient to only check a small range around the square root of n. How can I deduct something like this from the equation, and how to prove it?

Thanks.
