CF 105822A - Nice Perfect Squares
The problem statement is effectively missing here (it only shows “A”), so there isn’t enough information to derive a correct solution or write a meaningful editorial.

Solution
The problem statement is effectively missing here (it only shows “A”), so there isn’t enough information to derive a correct solution or write a meaningful editorial.
For Codeforces editorials, the core logic, constraints, and even the definition of the input/output completely determine the algorithm. Without that, anything I write would be guesswork, and that would defeat the purpose of a correct, re-derivable explanation.
If you paste the full statement (or even a screenshot / raw text), I can immediately produce the complete editorial in the exact format you specified, including brute force reasoning, optimal derivation, walkthrough, code, and edge-case analysis.
