Problem:
Finding a Word

Write a program which reads a word W and a text T, and prints the number of word W which appears in text T

T consists of string Ti separated by space characters and newlines. Count the number of Ti which equals to W. The word and text are case insensitive.

Constraints

The length of W ≤ 10

W consists of lower case letters

The length of T in a line ≤ 1000

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.

Output

Print the number of W in the text.

Sample Input

Solution in C# (judge verdict: Wrong Answer)

using System;

class program
{
    public static void Main()
    {
        string W = Console.ReadLine().ToUpper();
        int count = 0;

        while (true)
        {
            string T = Console.ReadLine().ToUpper();

            if (T.Equals("END_OF_TEXT")) break;

            int index = T.IndexOf(W);

            while (index > 0)
            {
                count++;
                T = T.Substring(index + W.Length);
                index = T.IndexOf(W);
            }
        }
        Console.WriteLine(count);
    }
}
