Ruby生成器

Question

我试图根据用户输入的名称和团队数量创建随机团队生成器。与此https://www.jamestease.co.uk/team-generator/

类似

到目前为止，我已将.split和.shuffle输入到names数组中，但不确定如何继续进行。

names = gets.split(",").shuffle

names = ["Aaron", "Nick", "Ben", "Bob", "Ted"]

例如：
 假设我想拥有2个团队（名称不必是任何特定的顺序/团队）：

team_1 = ["Nick", "Bob"]

team_2 = ["Aaron", "Ben", "Ted"]

非常感谢任何帮助或提示

Answer 1

names = ["Aaron", "Nick", "Ben", "Bob", "Ted", 'shiva', 'hari', 'subash']

number_of_teams = 4

players_per_team = (names.count / number_of_teams.to_f).ceil

teams = []

(1..number_of_teams).each do |num|
  teams[num - 1] = names.sample(players_per_team)
  names = names - teams[num - 1]
end

> p teams
=> [["hari", "Ben"], ["Bob", "subash"], ["shiva", "Ted"], ["Nick", "Aaron"]]

如果

names = ["Aaron", "Nick", "Ben", "Bob", "Ted", 'hari', 'subash']

然后

>   p teams
[["hari", "subash"], ["Bob", "Aaron"], ["Ben", "Nick"], ["Ted"]]

  

注意：每次洗牌都会导致随机玩家

Answer 2

使用Array#sample从names数组中选择随机元素：

> names = ["Aaron", "Nick", "Ben", "Bob", "Ted"]
# => ["Aaron", "Nick", "Ben", "Bob", "Ted"] 
team_size = names.length/2
# => 2
> team_1 = names.sample(team_size) # pick 2 random team names
# => ["Nick", "Ben"] 
> team_2 = names - team_1 # get the remaining team names from the names array
# => ["Aaron", "Bob", "Ted"] 

Answer 3

players = %w| Wilma Hector Alfonse Hans Luigi Bo Katz Themal Dotty Billy-Bob |

num_teams = 4

(players.shuffle + ["unfilled"]*(players.size % 4)).each_slice(num_teams).to_a.transpose
  #=> [["Katz", "Bo", "Hans"], ["Themal", "Luigi", "Billy-Bob"],
  #    ["Alfonse", "Hector", "unfilled"], ["Dotty", "Wilma", "unfilled"]]
