Solution in C# (judge verdict: Wrong Answer)

using System;

public class Test
{
	public static void Main( )
	{
		string w = Console.ReadLine().Trim();
		string input;
		int cnt = 0;
		while( null != (input = Console.ReadLine()) ) {
			string[] words = input.ToLower().Split( ' ' );
			for( var i=0; i<words.Length; i++ ) {
				if( -1 != words[i].IndexOf( w ) ) {
					cnt++;
				}
			}
		}
		Console.WriteLine( cnt );
	}
}
