Solution
The problem statement is missing, so I can’t reliably reconstruct what “Подсчет хештегов” (Hashtag counting) is asking for or what the required output format is.
Codeforces titles alone are not enough here, since similar-sounding problems can differ a lot (counting # characters, extracting hashtags from text, validating tags, or even processing multiple lines with constraints on punctuation).
Paste the full statement (or a screenshot / link text), and I’ll write the complete editorial in the exact format you requested.
