发帖数: 715 | 5 The big-O originally stands for "order of" ("Ordnung", Bachmann 1894), and
is thus a roman letter. Neither Bachmann nor Landau ever call it "Omicron".
The symbol was much later on (1976) viewed by Knuth as a capital omicron,[12
] probably in reference to his definition of the symbol Omega. The digit
zero should not be used. |

Most questions were in the previous posts of MITBBS.

So make sure search and read all 面经 of L before your interviews.

大学时候来米国，就发现米疣叫兽和作家喜欢故弄玄虚。
常常把简单的东西说成复杂，并且故意忽略关键部分。
而藤校学生也较自负虚荣，不懂装懂，怕被其它同学看衰。
这些叫兽也深谙学生的心理弱点，故意让它们没学到。
但我一般很快就问到关键的东西，每次他们都非常不爽。
愚蠢虚荣的狗蝇被耍了还敬仰万分，赞叫兽们高深莫测。
当然，如果你熟悉盗魔经，这一切都不奇怪，还可以预见。
盗魔经信徒对狗蝇没有好意，尤其最忌聪明本领的狗蝇。
