《算法導(dǎo)論(第4版)》閱讀筆記:p59-p75
《算法導(dǎo)論(第4版)》學(xué)習(xí)第 15 天,p59-p75 總結(jié),總計(jì) 17 頁(yè)。
一、技術(shù)總結(jié)
1. floor(向下取整) and ceiling(向上取整)
For any real number x, we denote the greatest integer less than or equal to x by ?x? (read 'the floor of x') and the least integer greater than or equal to x by ?x? (read 'the ceiling of x'). The floor function is monotonically increasing, as is the ceiling function.
二、英語(yǔ)總結(jié)(生詞:1)
1. save someone the trouble/bother (of doing sth)
(1)釋義
idiom. to do something so that someone else does not have to do it.
(2)示例
1)I'll make the appointment for you to save you the trouble/bother.
2)This convention saves us the trouble of naming the bounding constant, allowing it to remain anonymous while we focus on more important variables in an analysis.
上面這句話的意思是:這一約定省去了我們?yōu)榻缦蕹?shù)(bounding constant)命名的麻煩, 讓界限常數(shù)保持匿名使得我們?cè)诜治鲋心軐⒆⒁饬性诟匾淖兞可稀?/p>
