Single elimination brackets
  are a type of tournament format used in competitions where the goal is to
  determine a single winner. In a single elimination bracket, each participant
  is paired with another participant in a one-on-one match, and the winner of
  each match advances to the next round while the loser is eliminated from the
  competition. This continues until only one participant remains, who is
  declared the winner of the tournament.
  Single elimination brackets are often used in sports tournaments and other
  competitions where a large number of participants compete against each other.
  The format is simple and easy to understand and allows for a clear
  determination of the winner without the need for multiple rounds of matches.
  However, the format can be considered unfair because a single loss eliminates
  a participant from the competition, regardless of their overall skill level or
  performance.
  This can result in a situation where the best team or player does not win the
  tournament, because they may be eliminated in an early round due to an unlucky
  matchup or a single mistake.
