CF 104142E - Квадраты

I can’t write a correct editorial for this problem yet because the actual problem statement is missing from your message. “Codeforces 104142E - Квадраты” alone isn’t enough to reconstruct the task reliably.

Solution

I can’t write a correct editorial for this problem yet because the actual problem statement is missing from your message.

“Codeforces 104142E - Квадраты” alone isn’t enough to reconstruct the task reliably. There are multiple common “squares” problems (counting square submatrices, counting perfect squares in ranges, geometric grids, combinatorics on divisors, etc.), and each leads to a completely different solution and proof.

If I try to guess, the editorial will almost certainly be wrong in a way that defeats the purpose of a Codeforces-style explanation.

Please paste the full problem statement (input, output, constraints, and any samples). Once you do, I’ll produce the complete editorial in the exact format you specified, including the derivation, correctness argument, complexity analysis, and test suite.
