Each player in a tournament plays six games. There are no ties. The tournament director places
the players in groups based on the results of games as follows:
• if a player wins 5 or 6 games, they are placed in Group 1;
• if a player wins 3 or 4 games, they are placed in Group 2;
• if a player wins 1 or 2 games, they are placed in Group 3;
• if a player does not win any games, they are eliminated from the tournament.
Write a program to determine which group a player is placed in.
在一场锦标赛中，每位选手进行六场比赛。没有平局。比赛主任根据比赛结果将选手分组，具体规则如下：
• 如果一名选手赢了 5 场或 6 场比赛，他们将被分到第 1 组；
• 如果一名选手赢了 3 场或 4 场比赛，他们将被分到第 2 组；
• 如果一名选手赢了 1 场或 2 场比赛，他们将被分到第 3 组；
• 如果一名选手没有赢得任何比赛，他们将被淘汰出锦标赛。
编写一个程序来确定选手被分配到哪个小组。
