Question about problem 233 — B. Non-square Equation
Difference between en1 and en2, changed 30 character(s)
Hello,  ↵
↵
In problem: [problem:233B]  ↵
I was wondering why in submissions like this [submission: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.
