Solution
I can’t write a correct editorial yet because the actual problem statement is missing.
Right now the only content provided is the title “A”, so there is no way to know what inputs, outputs, or constraints look like for Codeforces 106289A (112358). Any attempt to continue would be guesswork and would likely produce an incorrect solution and reasoning.
Please paste the full problem statement (input format, output format, and constraints). Once you do, I’ll produce the complete editorial in the exact style you requested, including the algorithm walkthrough, proof sketch, complexity analysis, worked traces, and test cases.
