Problem Statement
In a tournament, every team plays exactly once against every other team. One won match earns points for the winner and for the loser. With a draw both teams receive point each. At the end of the tournament it appears that all teams together have achieved points. The last team on the final list scored exactly point. The second to last team has not lost a match.
a) How many teams participated in the tournament?
b) How many points did the team score in second place in the final ranking?
