/*
管道–過濾器之千年蟲問題
//////////////////////////千年蟲”問題的根源始於60年代。當時計算機存儲器的成本很高，如果用四位數字表示年 份，就要多佔用存儲器空間，就會使成本增加，因此爲了節省存儲空間，計算機系統的編程 人員採用兩位數字表示年份。隨着計算機技術的迅猛發展，雖然後來存儲器的價格降低了， 但在計算機系統中使用兩位數字來表示年份的做法卻由於思維上的慣性勢力而被沿襲下來， 年復一年，直到新世紀即將來臨之際，大家才突然意識到用兩位數字表示年份將無法正確辨 識公元2000年及其以後的年份。*************///////////////////////
