标 题: 昨天去REC跑步的时候看到老布什了
发信站: BBS 未名空间站 (Wed Apr 11 14:19:51 2007), 转信
昨天下午,去REC
REC外面停着两辆崭新的YUKON XL,一个黑的,一个maroon的,都是暴亮的,后窗贴
着厚厚的膜,司机似乎西装,感觉像是机构的车。
进了REC,看到两个西装墨镜帅哥(在REC的汗衫裤衩环境里,西装墨镜真的很扎眼
),中间夹着穿着破背心,裤衩,一瘸一拐的老布什,哥们竟然跑来锻炼来了。嘿
嘿。不过好像在REC的小朋友们都不知道老布什在,也没见到歌迷上去要签字啥的。
要是在大陆,赶上太上皇出来,是不是REC要全场清场,戒严,然后只让根正苗红的
人进去貌似锻炼啊。

上市公司的bank rec,几十页的bank statement,百万百万的balance?
每天都rec, 还是每周rec?
我帮客户做过的最大statement是30多页,一个月的,用了4个小时。因为不是上市公司
,discrepancies都放到一个clearing account, 到年底close到misc expenses。

Totally agree with Stone. For Bank Rec, the most challenging part is to find
what the transaction is for so you can know how to record it. I used to
reconcile about 27 bank accounts and were able to finish all the recs in 4
days since I had much more other duties to take care. The bank rec is boring
and so straight forward. Excel skills (such as Pivot table and VLookup) can
help you identify which transactions are recorded or not recorded quickly.

At this time, we believe that your background and qualifications would
make you a better candidate for REC’s Technology Department than Sales and
Marketing. Your resume has been forwarded to the Technology Manager, and we

yes, I do know the pains you have. I was doing over 20 bank rec in my

transactions that nobody knew what these were. Other than that, I would

试试G的题:
1. 二分找左右边界。
2. 常见题
3. 用一个collector收集结果,最底层的function:
isOverlapping(Rectangle a, Rectangle b)
collectCommon(ArrayList collector, Rectangle a, Rectangle b)
递归比较子节点,如果overlap, 进一步比较子节点,直到叶子,最后计算结果存入
collector。
4. 5.
6. DP
7. DFS
8. 计算P(i) = score(i)/sum(score[1..n]), 然后随机生成
9. 这个写起来最繁,45分钟内把头绪理清楚而且写清楚,我觉得很难,这是个大致框

来自主题: JobHunting版 - 这个copy random link真不容易写对
好吧,我写个copy random graph的通解,对一切graph,tree,list什么的都有效。
区别是O(n)space 复杂度。可以拿来救场。
标准list copy应该是O(n) time, O(1) space.
假设hash class, equal class已经定义好了。

if(root == 0)
return 0;
unordered_map::iterator it = rec.find(root);
if( it != rec.end()){
return it->second;
}else{
Node * newnode = new Node(root);// a new node, copy data
rec.insert(make_pair( root, newnode));
// then copy each ... 阅读全帖
