重复打印数组值'n'次

Question

我有以下数组：

arr = ['aaa', 'bbb', 'ccc']

如何在9次重复打印其值？

我试过以下它并且工作正常，但是任何更好的解决方案都值得赞赏：

total_elements = arr.length
new_index = 0
limit_value = 9

limit_value.times do |index|  
  if index < total_elements  
    new_index = index
  else        
    new_index = 0 unless new_index < total_elements    
  end  
  puts arr[new_index]
  new_index += 1
end

Answer 1

使用cycle + take

arr = ['aaa', 'bbb', 'ccc', 'ddd']

puts arr.cycle.take(9)
# >> aaa
# >> bbb
# >> ccc
# >> ddd
# >> aaa
# >> bbb
# >> ccc
# >> ddd
# >> aaa
