Q：Give a array of integers, remove all the duplicate.
我首先说sort array，然后比较当前和next，如果一样，就in place override当前，
最后array 就shrink到没有duplicate的了。面试官说sort too expensive.
接着，我说用map，如果insert过了，就 remove，他说hash expensive。
接着，我说用set，当insert int 到set 里有conflict stl会catch到，然后in place
override duplicate，面试官说set 还是用的hash，expensive，有可能collision，
hash不一定O（1）time complexity.
好像面试官一定要求不能extra time cost, space没有明确限制。
请问板上大神怎么破？
接下来，他又说，假如给你的array里面都是string呢？又怎么解？
Aube by Honeywell TI033/U 7-Day Programmable Timer Switch, White http://www.amazon.com/Aube-Honeywell-TI033-Programmable-Switch/dp/B000F3ZR8C/ref=cm_cr_pr_product_top
I was looking for a timer to control my outdoor lighting. I was first drawn
to this product because of the name Honeywell, which is well known quality
proven name in the PLC (Programmable Logic Controller) business. So if
Honeywell could make such a great PLC, then their timers should be par
excellence. It turned out that some rese... 阅读全帖

加钱没用。 non.negotiable restriction for 90 days buying. 不想等就把钱转出去换
别的的吧
You will be restricted from making day trades for 90 days in the instances
listed below. However, if you feel you must execute a sell order, you can
override these restrictions by calling our trade desk and speaking with a
broker. Please exercise discretion when overriding these restrictions
because doing so will result in a non-negotiable 90 day restriction from
buying stock.
How a Bill Becomes Law?
There are potentially 10 steps a bill can go through before becoming a law.
Below is a description of each step in the process, using the Genetic
Information Non-Discrimination Act of 2003 (S. 1053), as an example.
Step 1: A Bill Is Born
Anyone may draft a bill; however, only members of Congress can introduce
legislation, and, by doing so, become the sponsor(s). The president, a
member of the cabinet or the head of a federal agency can also propose
legislation, although a... 阅读全帖

更新一下，我的最后入境日期在H-1B批准之后，我问公司的律师说我入境时的F-1 I-94
会不会override那个在H-1B Approval Notice上的I-94，给我的答复是：
No, it does not override the I-94 on the H-1B since the H-1B I-94 only
begins on 10/01/2015.
不过还是谢谢楼上各位提供的信息

Wa, 當她的小孩很辛苦阿 Their preferences are often overrided; their fun is
based on hard work rather than play. 這是什麼樣的童年阿 呵呵
"What Chinese parents understand is that nothing is fun until you're good at
it. To get good at anything you have to work, and children on their own
never want to work, which is why it is crucial to override their preferences
."
