14. How to solve the problem of memory leaks in .net? Which tool is used to detect?
15. A look at the following code, you can simply think he is kind of what technology (skill), doing any good.

{
Private TemporaryFileSystem _fileSystem;
Public TemporaryFileSystem FileSystem
{
get
{
if(_fileSystem==null)
{
_fileSystem=new TemporaryFileSystem();
}
return _fileSystem;
}
}

17. The database, which has several index types? Talk about the principle of common database indexes and index implementation.
18. The most recent hits to write SQL
data table structure: SnapDayDoMainPV

Third, the programming section (C ++ programming language in Java or C # or any selection)
rule number one as follows: 1,1,2,3,5,8,13,21,34 ...... is seeking 30-digit number , implemented by a recursive algorithm.
The array of data stored in a certain set of types, implemented by sorting the array of generic types.
Fourth, the programming problem (brief write your design and analysis process, write simple code structure and logic)
cat screamed, all the rats are beginning to flee, the owner was awakened
requirements:
1. to have a linkage between mice and owner's behavior is passive.
2. Consider scalability, cat calls may cause other linkage effects.
