You have got 1 million parking slots. At a time a parking slot can be free or not. To get next slot easily which data structure to implement?

Posted By :Jean Paul     Posted Date :December 05, 2010    Points :15   Category :.NET Framework 
Use Stack.

If you use Stack, we can just get the next slot by using stack.Pop()

If you use List, we have to iterate through all list and check the status and retrieve.

So stack would be advantageous.

What is data structure?

  
A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data. (More...)

How is the data structure of System R different from the relational structure?

  
Unlike Relational systems in System R
1.Domains are not supported
2.Enforcement of candidate key uniqueness is optional
3.Enforcement of entity integrity is optional
4.Referential integrity is not enforced (More...)

Which is the suitable and efficient data structure to create a tree?

  
Linked list is the suitable and efficient data structure to create a tree. It will provide more flexibility. (More...)

can we connect two dataadapters to same data source using single connection at same time?

  
yes,we can connect two dataadapters to same datasource using single connection at same time.
There is a technology in ado.net 2.0 called MARS usinng Mars in connection string we can do it.
for eg:
cn.ConnectionString = "server=(local); database=employee; integrated security=sspi; MultipleActiveResultSets=True"; (More...)

What is JIT (just in time)? how it works?

  
Before Microsoft intermediate language (MSIL) can be executed, it must be converted by a .NET Framework just-in-time (JIT) compiler to native code, which is CPU-specific code that runs on the same computer architecture as the JIT compiler.
Rather than using time and memory to convert all the MSIL in a portable executable (PE) file to native code, it converts the MSIL as it is needed during execution and stores the resulting native code so that it is accessible for subsequent calls.
The runtime supplies another mode of compilation called install-time code generation. The install-time code generation mode converts MSIL to native code just as the regular JIT compiler does, but it converts larger units of code at a time, storing the resulting native code for use when the assembly is subsequently loaded and executed.
As part of compiling MSIL to native code, code must pass a verification process unless an administrator has established a security policy that allows code to bypass verification. Verification examines MSIL and metadata to find out whether the code can be determined to be type safe, which means that it is known to access only the memory locations it is authorized to access. (More...)

What is Method used to bind the data into gridview ?

  
DataBind() Method used to bind the data into gridview (More...)

What is the .NET that allows the retrieval of data by a unique key?

  
HashTable is the .NET collection class that allows the retrieval of data by a unique key (More...)

What is managed code and managed data?

  
Managed code is code that is written to target the services of the Common Language Runtime (see What is the Common Language Runtime?). In order to target these services, the code must provide a minimum level of information (metadata) to the runtime. All C#, Visual Basic.NET, and _JScript.NET code is managed by default. Visual Studio.NET C++ code is not managed by default, but the compiler can produce managed code by specifying a command-line switch (/CLR).
Closely related to managed code is managed data-data that is allocated and de-allocated by the Common Language Runtime's garbage collector. C#, Visual Basic, and _JScript.NET data is managed by default. C# data can, however, be marked as unmanaged through the use of special keywords. Visual Studio.NET C++ data is unmanaged by default (even when using the /CLR switch), but when using Managed Extensions for C++, a class can be marked as managed by using the __gc keyword. As the name suggests, this means that the memory for instances of the class is managed by the garbage collector. In addition, the class becomes a full participating member of the .NET Framework community, with the benefits and restrictions that brings. An example of a benefit is proper interoperability with classes written in other languages (for example, a managed C++ class can inherit from a Visual Basic class). An example of a restriction is that a managed class can only inherit from one base class. (More...)

List out the areas in which data structures are applied extensively?

  
1.Compiler Design,
2.Operating System,
3.Database Management System,
4.Statistical analysis package,
5.Numerical Analysis,
6.Graphics,
7.Artificial Intelligence,
8.Simulation (More...)

What are the major data structures used in RDBMS, Network data model & Hierarchical data model.

  
RDBMS - Array (i.e. Array of structures)
Network data model - Graph
Hierarchical data model - Trees (More...)

If you are using C language to implement the heterogeneous linked list, what pointer type will you use?

  
The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type. (More...)

What is the data structures used to perform recursion?

  
Stack. Because of its LIFO (Last In First Out) property it remembers its 'caller' so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls.
Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used. (More...)
