Re: [問題] 關於演算的觀念

21^F→neverfly:原來所謂的嚴格定義，是要嚴格定義在定義前面那句描述08/25 17:33

22^F→neverfly:而不是嚴格定義出定義本身，真是讓人大開眼界08/25 17:33

23^F→neverfly:演算法的定義本來就不止一種，怎能要求Knuth一定要說：08/25 17:34

24^F→neverfly:"Each step of an algorithm must be precisely defined"08/25 17:34

25^F→neverfly:這麼果斷的話？他底下的定義本身又哪裡沒有用強烈的字了?08/25 17:34

26^F→neverfly:就好像有人解了一題難題，然後補上："這是其中一種解法"08/25 17:36

27^F→neverfly:然後有人推論出："吼，這代表他的解法不夠嚴格"一樣奇怪08/25 17:36

[問題] 請教程設高手們～

3^F→neverfly:輸入可以不管，假設已經讀入，也可以做preprocessing08/21 18:15

4^F→neverfly:但字串內容是會變的08/21 18:15
