In a single elimination tournament, any player is eliminated with a single loss. The tournament is played in multiple rounds subject to the followings rules:

(a) If the number of the players, say n, in any round is even, yhen the players are grouped into n/2 pairs. The players in each each pair play a match against each other and the winner moves on to the next round.

(b) If the number of the players, say n, in any round is odd, then one of them is given a bye, that is, he automatically moves on to the next round. The remaining (n-1) players are grouped into (n-1)/2 pairs. The players in each pair play a match against each other and the winner moves on to the next round. No players gets more than one bye in the entire tournament

Thus, if n is even, then n/2 players move on to the next round while if n is odd, then (n+1)/2 players move on to the next round. The process is continued toll the final round, which obviously is played between two players. The winner in the final round is the champion of the tournament.

6. What is the number of matches played by the champion?

b. The champion received one bye.

 

7. If the number of the players, say n, in the first round was between 65 and 128, then what is the exact value of n ?

A. Exactly one player received a bye in the entire tournament.

B. One player received a bye while moving on to the fourth round from the third round.
