发帖数: 633 | 2 I know what the method is about, but it's not correct.
Say a1[]={5, 4, 1} a2[]={4, 3, 1} Then the result would be
5+4 = 9
5+3 = 8
4+4 = 8
4+3 = 7 //but in your method is either is 5+1 or 4+1
I have said that the problem with the approach is that there may be more
than 2 candidates for next pair.......
I know with Young talbe, we can get a O(n^2) solution...But how to get
better, like O(nlogn) is very difficult for me.... |

发帖数: 137 | 3 leetcode原题, permutation II和permutation sequence, 就是把int换成了char, 45
分钟的面试老中面试官大哥迟到5分钟, 却要按时结束, 加上闲扯几句, 这两题一共就
32分钟时间, 我自己感觉除了一点小typo之外没有问题啊, 那几个typo还是因为第二题
完全没时间检查了, 有他迟到的5分钟肯定能检查出来. 6个小时后就收到拒信, 而且我
用的C++, 感觉面试官对C++一点都不熟, 基本不说话, 我说好了后他也不review, 不作
评价,第二题还冒了一句std::set的元素是无序的, 你这样遍历得到的结果是随机的,
还浪费我时间跟他解释, 我汗...
下面贴上我的代码, 想请大家评评, 真心不懂为啥被拒, 能不能跟recruiter complain

This is the point why some customers "feel" cheated in mind, although it is

Before final talbe: I do not allin with anybody, just chips up by stealing blinds.And I have never raise Micheal Craig's blinds. When I saw Micheal Craig is in BB, I folded Ace 9 preflop. When he does not raise, and he is not in blinds, I raise with q7s.
Played 2 totally unnecessary hand, and get busted as 6th. Although I have the button, it is totally nonsense to be involved in such marginal situation.
If I do not play that 2 hands, just steal blinds. I am sure |

it's slow for the query, not generating HTML table, unless
you really have broken codes.
what you said here won't help because the first page still
needs that much time. |

发帖数: 29 | 38 Yes, for the first time, it will take time to retrieve all records
anyway.
But what I mean is I don't want to query database every time for some
records,
for example, for records 21-40, then 41-60. I want to save all retrieved
records
in a global array for the first time. Then I only show 1-20 records.
When user

instead of
querying database again, I just check the global array, and show the

发帖数: 28 | 39 This is not the way to implement next/prev pages for CGI programs.
The server is stateless, meaning that the data will be gone after
you serve the first request, unless you store it in some persistent
storage such as database, file or shared memory.
Come on, mysql is fast in doing simple queries and it has a syntax
that allows you to fetch certain number of rows which is specifically
designed for implementing next/prev pages. |

If a = 2,

If a = 1,

But if a != 1 or 2, does it has analytical solution or a talbe about it?
I think it is a classic problem, but can't find it via google, mathworld, etc.
