Replace Duplicate Words in Text

Description: This little function will replace duplicate words in a line or across multiple lines of text. For instance, if the text reads "What is the the color of the sky?" it will replace "the the" with "the". It will replace them even if the word at the end of a line is duplicated at the beginning of the next line. Uses the System.Text.RegularExpressions namespace.

Tested Platform: .NET 4.8, Visual Studio 2022, Windows 10

Language: C#

    Regex pattern = new Regex(@"b(w+)(s*$s*|s+)1b", RegexOptions.Multiline | RegexOptions.IgnoreCase);
    return pattern.Replace(inputText, @"$1");
