Solution
The problem statement is missing from your prompt, so I don’t actually know what “Codeforces 105484E - Left Shifting 3” is asking for. Without the definition of the operations, input format, and output requirement, any full editorial would be guesswork and very likely wrong.
If you paste the full statement (or even just the core description and constraints), I can produce the complete Codeforces-style editorial in the exact format you specified, including algorithm walkthrough, proofs, code, and tests.
Send the statement and I’ll take it from there.
