Lena is working on a utility for the internal platform that helps the team cycle through different testing sequences for their microservices. Mark reviewed the initial draft and suggested that the tool should always find the next logical arrangement of IDs to ensure every unique combination is tested in order. If the team has already reached the very last possible sequence, the utility needs to reset the IDs back to their original, lowest order. For example, if a developer is currently looking at sequence 2, 3, 1, the helper should automatically shift it to 3, 1, 2 for the next session.
