characters affected by addcslashes (). PS: be careful when applying addcslashes () to 0,r,n and T. In PHP, \0,\r,\n and \ t are pre-defined escape sequences. This function can be added to any character, including pre-defined characters, which is the difference from addslashes//Add a backslash to a specific character "Hello, my name is John Adams."; echo $str; echo addcslashes ($str,' m '); echo addcslashes ($str,' J ');Output:Hello, my name is John Adams.hello, \my Na\me is John A
For more information about users and groups, see Linux Enterprise Application-Linux server application. I recently learned how to configure the SMB service.
The general situation is as follows:
1. Each user has his/her own folder (private space by default)
2. Each department has an internal shared directory under which users in the Department can modify the files or directories they have created.
Other users in the Department only have the permiss

Title DescriptionGiven a number of 0-9 each. You can arrange these numbers in any order, but you must use them all. The goal is to make the last available number as small as possible (note that 0 cannot do the first). For example:Given two x 0, two 1, three 5, and one 8, the smallest number we get is 10015558.Now given the number, write the minimum number that the program output can consist of.Input Description:Each input consists of 1 test cases. Each test case gives 10 nonnegative integers in
In a recent hot discussion on eval, the instructors @ Franky and yanda @ otakustay also gave wonderful data analysis. Similar tests have just been done before, and I have also joined hands with others, two groups of data are provided for your reference. @ Lao Zhao's microblog "is the code generated by eval really inefficient? Http://t.cn/zWTUBEo contains personal attacks, do not like not ."
This has aroused recent discussions on eval, and the instruct
Groups strings by the specified number of strings.
The Code is as follows:
Static class Ulity{Public static string [] Split (this string source, int count){List String temp = string. Empty;If (source. Length % count! = 0)Source = source. PadRight (source. Length + (count-source.Length % count ));For (int I = 0; I {For (int j = 0; j {Temp + = source [I + j];}List. Add (temp );Temp = string. Empty;}Return list. ToArray ();}}
The running result is as fo

Assume that the table has a time field in Unix timestamp format. You need to calculate the number of records per day based on this field. Method: Use the convert function convert (char (10), time, 120) astime, and then groupbytime. Principle: The convert function converts the timestamp to the ODBC Standard Time (specified by the 120 parameter), and then takes the first 10 digits, which is just better.

Question http://poj.org/problem? Id = 2289
This is my first multi-match, so it feels good for other people's code.
Http://www.cnblogs.com/-sunshine/archive/2012/08/30/2664310.html
In fact, this multi-match is a bit like the idea of the Hungary algorithm.
A given list of n members should be assigned to M groups, and a possible group number should be given for each person, yes, the largest group is the smallest.
Idea: Multiple matching of one-to-multipl
GivenNPairs of parentheses, write a function to generate all combinations of well-formed parentheses.
For example, givenN= 3, a solution set is:

Convert to an undirected graph according to the meaning of the question, pre-process and remove one-way edge, and then determine whether the remaining graph can constitute two undirected full graphs (PS a full graph can also be a complete graph or a full graph + an orphan)
