CodeChefOpen on judge ↗

Amit has reached the finals of a Quiz contest. All the students were asked to prepare 10 topics for the final round. However, Amit has only prepared three topics, named X, Y and Z and he has no idea about other topics. This means Amit can only win the quiz if he gets the topics X, Y or Z. On the quiz day, Amit gets topic A. You have to determine whether Amit has any chances of winning the contest.
