I need help with fourms

var password = "hellofghjhello"; // get this from the form

foreach (var window in password.Window(3)) // Window is a custom extension method
{
    if (IsSequenceFromQwerty(window))
    {
        // You would probably just increment a count here and return the count, or do the score caluclations directly
        Console.WriteLine($"Found sequence: {window}");
    }
}

// this is the signature of the extension method
static IEnumerable<string> Window(this string source, int size)

var password = "hellofghjhello"; // get this from the form

foreach (var window in password.Window(3)) // Window is a custom extension method
