Regular expression from several words

Question

Hi all.

Please, can you help me to create a regular expression to get a string based on this query

Answer 1

An example:

string input = "Creativity is thinking-up new things. Innovation is doing new things!";
string result = Regex.Replace( input, @"(?<=\G.*\w)(\w*)(?=\w)", m => m.Value.ToLower( ).Distinct( ).Count( ).ToString("0;0;''" ) );

Console.WriteLine( input );
Console.WriteLine( result );

or:

string result = Regex.Replace( input, @"(?<=\G.*\w)(\w+)(?=\w)", m => m.Value.ToLower( ).Distinct( ).Count( ).ToString( ) );
