如果邻居白天弹钢琴,很吵得话,可以投诉吗?
实在受不了了,今天从8点半一直弹到现在,支离破碎的
她天天这样,不过我不放假的话,只用听一两个小时。
请问可以投诉吗?有没有消音器什么的可以用?
谢谢。

很多题目,结果要求没有重复的,比如3 sum,3 sum closest,还有combination,coi
change的。很naive的想法就是scan一遍已有的结果,看是否重复的;还有一个是用
set,但是这样insert的时候,也有cost吧?还有一种是程序中间保证没有重复的,这
都怎么弄呢?哪位大侠出来总结一下?

Sorry cannot type Chinese in the office.
My status changed from "fingerprint fee was received" to "Document Was
Mailed To Me". My PD is 10/12, RD 6/15. EB3 TSC. I asked State Senator to
contact TSC about 10 days ago.
What does it mean? Is it a RFE or a letter saying please keep waiting?

I got an email today saying the document was returned to USCIS by Post
Office because they cannot deliver it. So confusing.
I just called T2, she said their system is down today, she cannot see what
document was sent to me. She said probably the document was sent earlier and
returned but the online status didn't adjust right away and they resent it
today and the online status changed so I got an email about the returned
document earlier. Also it is possible a glitch of their system causing the
email by mistake.
No meaningful information from USCIS so far.
I really need some good luck!
