CF 1047755 - Перекресток

I can’t write a correct editorial yet because the actual problem content is missing. Right now you’ve provided the format and metadata for Codeforces 1047755 - “Перекресток”, but the statement, constraints, and sample I/O are not included.

Solution

I can’t write a correct editorial yet because the actual problem content is missing.

Right now you’ve provided the format and metadata for Codeforces 1047755 - “Перекресток”, but the statement, constraints, and sample I/O are not included. Without that, any solution would be guesswork, and for a Codeforces editorial that would quickly turn into something incorrect or misleading.

If you paste the full problem statement (or even just the core description plus constraints and samples), I’ll produce a complete editorial in the exact style you specified, including:

  • clean problem restatement
  • brute force → optimized transition
  • full algorithm walkthrough
  • Python solution
  • traces, edge cases, and complexity analysis

Send the statement and I’ll take it from there.
