Tideman is hard because it forces you
The Tideman solution, implemented in the CS50 course, offers a more sophisticated approach to voting. By using a ranked-choice system and a series of instant runoffs, the Tideman solution provides a more accurate representation of voter preferences. As we continue to develop and refine our democratic systems, the Tideman solution serves as an important example of how technology can be used to improve the voting process. By using a ranked-choice system and a series

The correct check is:
After adding winner→loser, does loser have a path to winner in current locked graph? Yes → cycle.
