L33t Tr4nsl4t0r (Leet Translator)

This is a little funny method that changes text to Leet[^] text. It is a C# version of a website[^] translator.

To use it, just call the static method Translate that takes two parameters: a string that has to be translated to Leet and an integer that tells the degree of translating.

// Original text
string myText = "Leet Translator";

// Translated text
string leetText = Leet.Translate(myText, 30);

// Output is: L33t Tr4nsl4t0r
Console.WriteLine(leetText);

// Do it again, and change degree to 100.
string leetText = Leet.Translate(myText, 100);

// Output is: £337 7®4|\|$£470®
Console.WriteLine(leetText);

// Leet class has an extension method to string class that allows us to
// Output is: L33t Tr4nsl4t0r
Console.WriteLine(myText.ToLeet());

Here is the Leet class:

public static class Leet
{
    /// <summary>
    /// Translate text to Leet - Extension methods for string class
    /// </summary>
    /// <param name="text">Original text</param>
