A Single-Elimination Tournament is a type of competition where participants are eliminated after losing a match. Each match is a knockout round, meaning that the winner advances to the next round while the loser is out of the tournament. This format continues until only one participant remains, who is declared the champion. In a Single-Elimination Tournament, the number of rounds depends on the total number of participants. For example, with 8 participants, there will be 3 rounds: quarterfinals, semifinals, and finals. This structure is commonly used in sports, games, and various competitive events for its simplicity and excitement.
