ruby - 如何使用 ARGV*，我如何在其中实现命令行参数

Question

<<-doc 为传递给此方法的任意数量的时间值修改时间总和方法。例如：("11:23:07","22:53:45","0:23:23","23:45:56") -> "2 天 & 10:26:11" ("0 :45:34","0:15:58") -> 01:01:32 ; ("11:23:07","22:53:45") -> 1 天 & 10:16:52 文档

但我希望它为 2 [/name] [input] "24:01:10" "10:30:50" [/input] [output] "Invalid 24-hour time value" [/output]

===

[名称] 3 [/名称] [输入] "0:45:34" "0:15:58" [/输入] [输出] "01:01:32" [/输出]

把 sum_time("11:23:07","22:53:45","0:23:23","23:45:56 enter code here")

如何在脚本中使用 ARGV：

require 'time'
def to_seconds(timestamp)
  timestamp.hour * 3600 + timestamp.min * 60 + timestamp.sec
end
def sum_time(*time)
  # initialize the variables
  total_seconds = 0
  time.each do |time_item|
    timestamp = Time.parse(time_item)
    total_seconds += to_seconds(timestamp)
  end
  sum_time_string = ""
  days = (total_seconds / (24 * 3600)).to_i
  sum_time_string = "#{days} day & " if days > 0
  sum_time_string += Time.at(total_seconds).utc.strftime("%H:%M:%S")
end
puts sum_time(*ARGV)
