I used C# language to implement Selection sort algorithm.
public class SelectionSort
{
private static void SortSelection(int[] input, int n)
{
for (int i = 0; i < n - 1; i++)
{
var minId = i;
int j;
for (j = i + 1; j < n; j++...

It is common practice to create groups of items by creating simple value nodes with item ID as key. For example, we can add a user to the group "administrators" by creating a node at /administrators/$user_id with a value true. We don't want anyone to know who administrators are, for securi...
Dim count As Integer = 0
Dim message As String
If count = 0 Then
message = "There are no items."
ElseIf count = 1 Then
message = "There is 1 item."
Else
message = "There are " & count & " items."
End If
9.0
If(condition > value, "True", "False")
We can use the If operator instead of If...Then...Else..End If statement blocks.
Consider the following example:
If 10 > 9 Then
MsgBox("True")
Else
MsgBox("False")
End If
is the same as

The default Django project template is fine but once you get to deploy your code and for example devops put their hands on the project things get messy. What you can do is separate your source code from the rest that is required to be in your repository.
You can find a usable Django project templ...
Options have a flatMap method. This means they can be used in a for comprehension. In this way we can lift regular functions to work on Options without having to redefine them.
val firstOption: Option[Int] = Option(1)
val secondOption: Option[Int] = Option(2)
val myResult = for {
firstValue ...

Using an Asynchronous Controller in ASP.NET MVC. The AsyncController class enables you to write asynchronous action methods. You can use asynchronous action methods for long-running, non-CPU bound requests. This avoids blocking the Web server from performing work while the request is being processed...
The ConstainsKey method is the way to know if a key already exists in the Dictionary.
This come in handy for data reduction. In the sample below, each time we encountner a new word, we add it as a key in the dictionary, else we increment the counter for this specific word.
Dim dic As IDictionary(...
Pancake Sort is a the colloquial term for the mathematical problem of sorting a disordered stack of pancakes in order of size when a spatula can be inserted at any point in the stack and used to flip all pancakes above it. A pancake number is the minimum number of flips required for a given number o...
To call a list of goals as if it were a conjunction of goals, combine the higher-order predicates call/1 and maplist/2:
?- Gs = [X = a, Y = b], maplist(call, Gs).
Gs = [a=a, b=b],
X = a,
Y = b.
