Solution

I can’t reliably write a correct editorial for Codeforces 103449D - Updating Inversions without the actual problem statement.

This particular ID doesn’t match a standard public CF problem I can reconstruct with confidence, and guessing would risk inventing constraints or mechanics that don’t exist (especially dangerous for inversion-update problems, where a small detail changes the whole solution).

Send the full statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact style you requested, including the algorithm walkthrough, proofs, code, and edge-case traces.
