Solution in C# (judge verdict: Wrong Answer)

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        string W = Console.ReadLine();
        W = W.ToLower();
        string T = Console.ReadLine();
        T = T.ToLower();
        string W2 = " " + W + " ";
        MatchCollection match = Regex.Matches(T,W2);
        Console.WriteLine(match.Count);
    }
