Solution

The problem statement you provided is incomplete (only “I” is shown, with no description of input/output or task). Without the actual definition of what “Saki and Encoding” is asking, any editorial would be pure guessing, and that would defeat the goal of a correct Codeforces-style explanation.

If you paste the full statement (or even a screenshot/text dump), I can immediately produce a complete editorial in the exact format you requested, including the algorithm walkthrough, proofs, and implementation.

Send the full problem and I’ll continue from there.
