Solution
The problem statement section is empty, so there is no information about what “103999C - Prime” is actually asking. Without the definition of the input format, the required output, and the operation being performed, any editorial would necessarily be guesswork, and that would defeat the purpose of a Codeforces-style explanation.
To write a correct and useful editorial, I need the full problem statement, including what the input represents, what needs to be computed, and any constraints. If there are samples or a link to the original problem page, that would also help ensure the solution matches the intended task.
Once you provide that, I can produce a complete step-by-step editorial in the exact format you specified.
