For N = 2017 also, all can be liars as well since each liar will call another liar as truth teller.

[@utkarsh8885]

It is told in the question that there is atleast one truth-teller and atleast one liar in the circle

[@globalolympiadsacademy4116]

@@utkarsh8885 I know but the example showed in 2017 case was only demonstrated by saying that all will be truth tellers..all can be liars also....that should have been demonstrated as well...that's all .the solution else is very nicely explained

[@pranavsawantcoder]

Yes precisely, all can be liars as well. In either scenario, N=2017 fails
