就是实现一个strchr，只不过第二个参数不是字符，而是字符串，返回第一次出现的指

/*
Find the first occurrence in str of _any_ character in set. Both are NULL
terminated ASCII C-strings. This is like strchr, except that the second
parameter functions as a set, rather than a single character.
str set returns
qxcdef csz str + 2 == &str[2]
axcdef wya str + 0 == &str[0]
axcdef cxa str + 0 == &str[0]
abc efg NULL
*/
这个就用一个hashtable做就可以了。结果麻烦开始了，他说用unicode怎么样，结果我
对unicode完全不了解，他就开始解释，就说unicode一个字符可能用1-5个char来表示
？那我就说假设有一个table帮你判定是不是unicode，那么就像wordbreak那个题一样
，往前走 碰到完整的unicode就记下来。
结果他说
ㅈㅏㅇㅏ ！= 장ㅏ
那我说怎么确定这个字符串的分割方式啊。。弄了半天。。然后他又说用_分割，因为
时间很紧张了，我就照这个意思简单地写了下code。应该让他举一个完整的例子的。写
完了他有点不置可否。
可能是因为时间不够，就用了10多分钟问了些简历，回答的也不算很好，就结束了。
有人能讲讲unicode用c字符串来表示是怎么个情况么。。
结果的话，估计是攒rp了。 |

even you do not have an idea of the detail of UTF8 implementation - which is
almost the standard encoding nowadays, there is no excuse that you know
nothing about what is an encoding.

a special character like '_'to parse the unicodes.So now I should get
rejected because this is different from the real implementation detail?

或者根本不会考。

发帖数: 7881 | 78 now u know CS is not that easy... the best route is to enter one of those
FLAGT, even ebay, msft companies, and then work on a hot technology, then
after couple years, u can get a real big package. Those fresh graduate who
got into FLAGT aren't necessarily better than u, maybe the timing, maybe
they got lucky with the questions.
But if u are unlucky after graduation, or just didn't care about hot tech
companies after graduation, then u work for several years in a cold-tech
company, then good luck. It would be even harder to switch to a hot tech
company as an "experienced"...

I won't buy this anyway.I would say: if I were as competitive as 大牛s like

be some luck.
By the way, I still don't think you got rejected( if this happens ) just
because you are experienced.It doesnt make any sense.

发帖数: 7881 | 81 no, i never said it's all about luck. Those fresh grad who enter hot tech
companies are good, some maybe execellent. But so are many other "good"
fresh grads who didn't get to enter those hot tech companies.
regarding the experienced shit, u will understand when u have some
experience urself. First, as an experienced, ur interview questions are
harder. secondly, people tend to either hire a clean slate (fresh grad
hires) or someone with a very similar experience (experienced hires). For
experienced hires, people tend to look at what u've done, what industry u've
been... and of course, when people look at me, they wonder why is she
still a bottom feeding IT tech...
