1. **Python portion (first part)**: ```python ...

Python portion (first part):

a = [1, 2, 3]
b = [2, 3, 4]
c = set(a) & set(b)

• What this does:
  • a and b are created as lists containing integers.
  • set(a) and set(b) convert the lists into sets.
  • The & operator computes the intersection of the two sets, i.e., the common elements between a and b.
  • The resulting intersection, {2, 3}, is assigned to c.
• Result: After this code, c will be a set containing the common elements {2, 3}.

C# ASP.NET Core Application Code (second part):

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllersWithViews();

var app = builder.Build();

if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

// Define default route
app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

• What this does: This is a startup configuration for an ASP.NET Core web application:

  1. Setup:
     • WebApplication.CreateBuilder(args): Initializes the builder for the application.
     • builder.Services.AddControllersWithViews(): Adds support for controllers and MVC views.
  2. Building and Middleware:
     • app.UseExceptionHandler, app.UseHsts: Enables error handling and HTTP Strict Transport Security in non-development environments.
     • app.UseHttpsRedirection: Redirects all HTTP traffic to HTTPS.
     • app.UseStaticFiles: Enables serving static files like CSS, JavaScript, and images.
     • app.UseRouting: Sets up routing for the application.
     • app.UseAuthorization: Adds authorization middleware for protecting routes.
  3. Routing:
     • app.MapControllerRoute(...): Configures default routing to map URLs to the HomeController and its Index method.
       • Example: A URL like / would route to HomeController with the Index action.

• Result: This code defines an ASP.NET Core web application that supports MVC, serves static files, handles routing, and uses HTTPS. It runs the application with the default route {controller=Home}/{action=Index}/{id?}.
