Input

In the first line, the word W is given. In the following lines, the text T is given separated by space characters and newlines.

"END_OF_TEXT" indicates the end of the text.

Solution in C# (judge verdict: Wrong Answer)

using System;

public class hello
{
    public static void Main()
    {
        var bunsho = "";
        var w = Console.ReadLine().Trim();
        while (true)
        {
            var s = Console.ReadLine().Trim();
            if (s == "END_OF_TEXT") goto readend;
            bunsho += s;
        }
        readend:;
        var buf = bunsho.Length - bunsho.Replace(w, "").Length;
        Console.WriteLine(buf / w.Length);
    }
}
