发帖数: 60932 | 1 Complete Rifle Plum Crazy AR15 Lower with 6 position M4 Collapsible Stock
with CMMG M4 Upper $599
First attempt at a post. For all my gun advocates. A solid deal, on a solid
weapon.
Plum Crazy lower in 5.56 with collapsible 6 pos. stock and CMMG lower
assembly. As I understand, they are complete assemblies to make the weapon
whole. Link fails to mention a trigger parts group from what I read, yet
does implicate COMPLETE rifle. Has to be worth the investigatio n for
someone, as it is a nice comb |

Mar 1, 2018, 17:40 PM
【侨报纽约网报道】大都会博物馆实行强制票价了！没关系，这里还有一份纽约最
全的博物馆(公园)免费参观指南。
据纽约时报报道，纽约大都会博物馆3月1日起实施强制门票规定，无法提供居住在
纽约州证明的游客将固定收取25美元门票费用。12岁以下儿童仍可免费参观；纽约州、
新泽西州和康州的学生持证件也仍按建议票价的方式购票，即可以按自己意愿随意支付
。三州以外的学生票价被定为12美元，老人票则为17美元。
此前，大都会博物馆自1870年开放以来，一直采取建议票价的方式，允许游客按意
愿随意支付，就是说你就算只花1美元也可以参观。
和华盛顿不同，纽约很多优秀的博物馆都不是免费开放的，虽然很多博物馆采取建
议票价的方式允许游客随意支付，但如果能大大方方的免费参观，总比心里七上八下怕
给多了吃亏给少了又没面子的好不是？
幸好，我们还有一份从NYCgo整理到的博物馆(公园)免费参观指南，只要选择正确
的时间去对的博物馆就好。需要注意的是，以下免费入场的许可只是普通门票，特殊展
厅或特别活动仍需要另外购票。

int lower = Math.max(0, k-b.length-1);
int upper = Math.min(a.length-1, k-1);

发帖数: 1145 | 31 LZ，32 的 super cool 应该是 32 才对吧？
因为 32 = 2^5.
刚写了一个程序，利用 binary search 的思路.
首先选定一个 upper bound，也就是 ceiling(log(n)).
然后再 i=2 到 upper bound 每一个做 binary search.
例如，n=32，upper bound = log(32) = 5.
i=2，从 low = 1 到 high = ceiling(n^(1/2))
i=3, 从 low = 1 到 high = ceiling(n^1/3))
..
以此类推...
binary search 的 invariant 就是比较 target 和 middle and middle's next，看哪
一个比较近。如果是离 middle 比较近，那就 middle's next 和它上边的值都可以抛
掉了。相反，那就 middle 和它下边的值就可以抛掉。
这里，我们确保 middle's next 不会大于 high。这个条件可以保证，因为取的是
lower middle = (L+H)/2.

Yes. Some companies sell uppers without a BCG and charging handle so that
they can sell them for $150 less. That is really sad because the bolt needs
fitted to the barrel and the head space checked. So it would cost you

int low = findLeft(a, value, 0, a.length);

他们给的这个lintcode 的参考答案， 比我写的还乱，看了就头疼。
这个是我的，
for(int i=0;i
if (i >= k) {
lower.remove(i-k);
upper.remove(i-k);
}
lower.add(i);
while( lower.size() > upper.size()-1)
upper.add(lower.poll());
while( lower.size() < upper.size())
lower.add(upper.poll());
if (i>=k-1)

发帖数: 4 | 50 这个题目可以从高位到低位，逐个确定位的value，每个位只能是3或者5，如果是小于
33333。。。，那么就输出33333.。。。如果小于35555.。。， 那么确定最高位位是3
，否则这个位就是5。然后记录下来，再推下一个。
public static int largerInteger(int num) {
int digits = 1;
int d = 1;
int upper = 5; // for value boundaries.
int lower = 3;
while (num / d >= 10) {
digits++;
d *= 10;
upper = upper * 10 + 5;
lower = lower * 10 + 3;
}
if (num >= upper) return lower + 3 * d * 10;
if (num < lower) return lower;
int curV = 0;
