请不要嘲笑我的无知,我在看cc150的时候,给的答案都是用LinkedListNode,但是我
在java编辑中,LinkedListNode 下面是红色的波浪,说没有此定义的class。我在网上
搜索 找到了 http://fisheye.igniterealtime.org/browse/openfire/trunk/src/java/org/jivesoftware/util/LinkedListNode.java?r=13651&r=13651 这个网址,我下载了这里得linkelistnode得定义。感觉还是不对。
根据我对答案的理解,她用的是一个双向链表,于是我写了这个class:
package cc150;
public class dNode {
private dNode pre = null;
private dNode next = null;
private int data;

dNode(int data){
this.data = data;
}

void addNode(dN... 阅读全帖

purpose: 想要做一个macro 循环调用 display, 输出不同的 survey answer as text,
然 后再根据其内容,人工的输入yes/no,以便于以后的数据分析。
problem: 整个 macro 可以运行,唯一的问题是,display 的 window 在循环调用的时
候不能正确的显示 survey answer. (我是将所有的 survey answer 输出到一连串
macro variable 里面去)。
Any solution or suggestion in proving the code is appreciated

There are two cases I know of
1. Return parameter cannot be specified at parent. For example,
class ComponentSampleModel; //parent
class ByteComponentSampleModel extends ComponentSampleModel
{
public byte[] getData ();
}
class ShortComponentSampleModel extends ComponentSampleModel
{
public short[] getData ();
}
// also int version
Parent knows exactly what the possible children are (byte, short, int),
can code algorithms in one place (rather than repeated 3 times) at

来自主题: JobHunting版 - google onsite杯具+设计题怎么答
一共5个人,其中3.5个人考coding,数据结构和算法。1.5个人考设计。
coding考了recursion, DP, 二叉树bfs,简单的hash一类的。因为写程序比较快,一共
答了7,8道coding题,难度不超过cracking the code,感觉基本答得还可以,难一点的
题bug还算少,而且跟面试官解释了一些边界情况为什么没有比这么写更简洁的方法,
除了最后一个面试官很变态。考了两个很简单无难度的code让写,顺序写完(不给时间
检查)以后叫不许动,拍照,然后说你的code有bug,虽然我很快给找出来了,但是给
拍照了。其实最后一个面试官的时候已经有点晕了,他早点说需要一次写对我就会写慢
些,可是他也没有说。。。
然后栽在一道large scale的设计题上。绝对不是所有的面试官都让你随意发挥,有的
人心里装了一个答案,问的很模糊,你不答到他那个答案他就是不满意。不知道如何解
决这种情况。大概问答过程如下:

来自主题: JobHunting版 - google onsite杯具+设计题怎么答
说说我看到你答案的感想吧:
He: how would you design a distributed key-value store
Me: DHT or just using clusters
我不知道这一问一答是你简化过了还是实际就这么简单。如果实际就这么简单,
回答就很有问题。一般问一个设计题,是先要把问题的各种要求先和面试官讨
论清楚。你这么回答就好像考官问如果搜索速度太慢怎么办,你回答说用
cache一样(正确的回应是先讨论哪个环节慢了)。而对于这个问题我觉得首
先应该问清楚这个系统有多大,有多少Machine,有没有balance的要求,会
不会add或者delete整个machine,等等。
然后,即使在问清楚条件的情况下,也不要马上给一个specific的方案,而是
依旧泛泛地谈大致有几类思路。然后根据考官的反应,再说具体的技术细节。

来自主题: JobHunting版 - 2 Sigma的onsite面经
1, 问了Evaluate Reverse Polish Notation的题目,但是并不是仅仅做一个函数算出
答案,而是说你要怎么样设计各个class,以及互相之间怎么联系。
2, 假设有两个Queue,不停的在进出数据。每个有一个getdata()的函数,返回一个数
据包括了时间以及一个字符串。如果从Queue1的数据的时间和Queue2的数据的时间相差
1秒的话,把两个字符串输出。
3, 如果我有一个网站,卖东西的,跟Amazon差不多这种,然后用户再抱怨我的网站非
常慢,然后聘了你当技术总工,你要怎么样改进?
4, 给一个日期,用字符串表示,比如20140608,求这个日期所在的星期的最后一天。
先说了说算法,然后再到机器上实际把这个已经有的程序debug出来。
求教应该什么方向去学习。尤其对于第3题,应该怎么解答。

The "standard" solution is to use
Object getData()
Since you are using primitive array and reflection you have to cast it anyway.This way you don't need reflection.
