演示代码： [code] #!/usr/bin/env ruby COUNT = 10 require 'benchmark' $account_chars = ('A'..'Z').to_a.delete_if {|c| c =~ /[AEIOUY]/ } #$password_chars = ('0'..'9').to_a $password_chars = Array.new $password_chars[0..9] = ('0'..'9').to_a $password_chars[10..36] = ('A'..'Z').to_a def account_char $account_chars[rand($account_chars.length)] end def password_char $password_chars[rand($password_chars.length)] end def account_chars account_chars = [] 6.times {|c| account_chars << account_char } account_chars end def password begin begin password = '' password << password_char end while password == '0' 4.times { password << password_char } end while password =~ /^(.)1111$/ password end accounts = {} lines = [] puts Benchmark::CAPTION puts Benchmark.measure { COUNT.times do i = 0 account_chars.inject(accounts) do |a, c| i += 1 i == 6 ? a[c] = password : a[c] ||= {} end end } puts Benchmark.measure { accounts.each do |char, chars| account = [char] chars.each do |char, chars| account << char chars.each do |char, chars| account << char chars.each do |char, chars| account << char chars.each do |char, chars| account << char chars.each do |char, password| account << char lines << "#{account.join}t#{password}rn" account.pop end account.pop end account.pop end account.pop end account.pop end end } puts Benchmark.measure { open 'account.txt', 'wb' do |f| f.print lines.delete_at(rand(lines.length)) until lines.empty? end } 运行后输出到： account.txt文件中。 输出信息格式如下： 数据是随机的，所以每次的记录都会不同。 SZQGMC XC6KP HLVGTZ HCU30 KTSNNF LSNVS KWMHRQ 3SM07 BTTZCZ DYMUH DMKPVN GMJHL KCFKDR X8X8V VMMJHB X1D65 SRCPGZ T2IP6 WLRMBT 7YA2Y
