Solution

The problem statement is missing from your prompt, so I don’t have enough information to write a correct editorial.

“Shortest Substring” is a very generic title, and Codeforces problems with similar names vary a lot (some are about distinct characters, some about covering patterns, some about lexicographic minimization, etc.). If I guess, the entire editorial would be unreliable.

Please paste the full statement, including input/output format and constraints, and I’ll write the complete Codeforces-style editorial in the format you requested.
