发帖数: 75 | 1 [CSTR] No need to introduce this ticker.
In 2007, I was a member of the Blockbuster DVD rental service. I hated the way they charged for
rentals. Unless you have a big family or friend network to share your cost,
it makes no sense to pay ~5 bucks to keep the DVD for 5 days.
In 2008, I registered an account with Netflix(NFLX). HDDVD and BD was still
in the format war. I did not think NFLX would do so well in the near term. I
did not like the DVD mailing service so much because I feel entertainmen... 阅读全帖 |

发帖数: 298 | 2 我说的就是copy cstr和dstr。TIC是thinking in C++吗？如果copy cstr不new,那么谁
应该delete呢？提供一个clear()让user调用吗？能不能讲讲不应该new的情况是怎么样
的？ |

个删除另一个会出问题。为什么很多书里都没有这两个函数呢？ |

发帖数: 452 | 11 How about this version using Dynamic Programming?
The basic idea is fill in a table for a matching path. If the last pair
matches, the whole string will match.
mtch is the array, which is of (string length + 1)*(pattern length + 1).
mtch[0][*] and mtch[*][0] is padded with false.
Then the function is something like:
mtch[i][j] =
1. if pattern char='.', mtch[i][j]=mtch[i-1][j-1]
2. if pattern char='*', mtch[i][j]=mtch[i-1][j-1] || mtch[i][j]=mtch[i-1][
j]
3. if pattern char=string char, mtc... 阅读全帖 |

Added more test cases like:

string = "a", pattern = "aa"
string = "aa", pattern = "a"
Code:

发帖数: 240 | 17 Edit： 好像不对，还是更复杂的情况。
想了一个O（n）的解法。请帮忙看一下对不对。
if A and B have no duplicate char: easy problem. just traverse C. increase A
's
index if A's char matches or increase B's index if B's char matches.
if A and B have duplicate chars, we assume A[i, j] == B[m, n].
when we traverse C and in the position where C[k] == A[i] == B[m], we have
two ways to go: increase A's index or increase B's index. in this kind of
situation, we will always select to increase A's index.
if we are lucky, A is the right way to ... 阅读全帖 |

标 题: 抽空说说我炒股的基本原则
发信站: BBS 未名空间站 (Fri Mar 27 22:40:20 2015, 美东)
不一定对，仅供大家参考，我很鼓励每个人都写写自己的炒股心得策略什么的，总之希
望多一些干货。
1、图形为王。不管是短期投资还是长线投资，个人觉得图形比其他信息都重要。其实
这个和价值投资并不矛盾，试想一个基本面真如我们看到的数据那么好的股票却连续的
喋喋不休，你信么？反正我不信，图形好的股票一定是阳多阴少阳长阴短的，这样的股
票做起来是令人放心的。
2、谁笑到最后谁才笑得最好。开盘涨不算涨，收盘涨才是涨。这一点我说过很多次就
不重复了。
3、高抛低吸，先玩不要追涨，即使是知道这个股票随后会大幅度上涨，也一定要等他
短暂的回调才介入，这一点很重要，这就和我们去市场买菜讨价还价一样，购买价格越
低肯定对我们越好。
其实这些都是最基本的操作，但是真正做起来其实并不容易，我个人分析最主要的原因
就是我们的感官容易被股价的波动所感染，不能像一台机器那样工作，很多时候看不得
