Radix Sort is lower bound comparison based algorithm. It is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys by individual digits which share some significant position and value. Radix sort is a linear time sorting algorithm that sort in O(n+k) time whe...
When called without arguments, Node.js starts a REPL (Read-Eval-Print-Loop) also known as the “Node shell”. At a command prompt type node. $ node > At the Node shell prompt > type "Hello World!" $ node > "Hello World!" 'Hello World!'
Git config allows you to customize how git works. It is commonly used to set your name and email or favorite editor or how merges should be done. To see the current configuration. $ git config --list ... core.editor=vim credential.helper=osxkeychain ... To edit the config: $ git config &lt...
Diamond problem is a common problem occurred in Object Oriented Programming, while using multiple-inheritance. Consider the case where class C, is inherited from class A and class B. Suppose that both class A and class B have a method called foo(). Then when we are calling the method foo(), compil...
Method overloading is the way of using polymorphism inside a class. We can have two or more methods inside the same class, with different input parameters. Difference of input parameters can be either: Number of parameters Type of parameters (Data type) Order of the parameters Let's take a ...
The Memory Model is difficult to understand, and difficult to apply. It is useful if you need to reason about the correctness of multi-threaded code, but you do not want to have to do this reasoning for every multi-threaded application that you write. If you adopt the following principals when wri...
If you want to do different things based on the kind of error, use multiple rescue clauses, each with a different error type as an argument. def divide(x, y) begin return x/y rescue ZeroDivisionError puts "Don't divide by zero!" return nil rescue TypeError put...
You can read content of file using OPENROWSET(BULK) function and store content in some table: INSERT INTO myTable(content) SELECT BulkColumn FROM OPENROWSET(BULK N'C:\Text1.txt', SINGLE_BLOB) AS Document; SINGLE_BLOB option will read entire content from a file as single cell. ...
You may want to read a DataFrame from a CSV (Comma separated values) file or maybe even from a TSV or WSV (tabs and whitespace separated files). If your file has the right extension, you can use the readtable function to read in the dataframe: readtable("dataset.CSV") But what if your ...
Data sets often contain comments that explain the data format or contain the license and usage terms. You usually want to ignore these lines when you read in the DataFrame. The readtable function assumes that comment lines begin with the '#' character. However, your file may use comment marks like ...
This example show how one may create a simple "Hello World" in Gtk3, setting up a window and button widgets. The sample code will also demonstrate how to set different attributes and actions on the widgets. module Main (Main.main) where import Graphics.UI.Gtk main :: IO () main = d...
Method overriding is the way of using polymorphism between classes. if one class is inherited from another, the former (sub class) can override the latter's (super class's) methods, and change the implementation. this is used where the super class defines the more general implementation of the meth...
LINQ extension methods on IEnumerable<T> take actual methods1, whether anonymous methods: //C# Func<int,bool> fn = x => x > 3; var list = new List<int>() {1,2,3,4,5,6}; var query = list.Where(fn); 'VB.NET Dim fn = Function(x As Integer) x > 3 Dim list = New List F...
Add the readonly attribute to prevent user input. A readonly field can't be edited <input class="form-control" type="text" placeholder="Readonly input here…" readonly> Add the disabled attribute to disable an input field. A disbled field can't be edited either...
$url1 = [uri]::EscapeDataString("http://test.com?test=my value") # url1: http%3A%2F%2Ftest.com%3Ftest%3Dmy%20value $url2 = [uri]::EscapeUriString("http://test.com?test=my value") # url2: http://test.com?test=my%20value # HttpUtility requires at least .NET 1.1 to be instal...
Note: these examples use the variables created in the Quick Start: Encoding section above. # url1: http%3A%2F%2Ftest.com%3Ftest%3Dmy%20value [uri]::UnescapeDataString($url1) # Returns: http://test.com?test=my value # url2: http://test.com?test=my%20value [uri]::UnescapeDataString($url2) # Re...

You can return a list of all the messages in a mailbox using imap_headers. <?php $headers = imap_headers($mailbox); The result is an array of strings with the following pattern: [FLAG] [MESSAGE-ID])[DD-MM-YYY] [FROM ADDRESS] [SUBJECT TRUNCATED TO 25 CHAR] ([SIZE] chars) Here's a sample o...
Each control has a property DataBindings which is a list of System.Windows.Forms.Binding objects. The Add()-method has some overloads which enables you easily binding to the property of an object: textBox.DataBindings.Add( "Text", dataObj, "MyProperty" ); Note, that binding b...
