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 Problem {
    public static int CountOf(string str, string target) {
        var c = 0;
        var index = str.IndexOf(target, 0);
        while (index != -1) {
        	c++;
        	index = str.IndexOf(target, index + target.Length);
        }
        return c;
    }
    public static void Main() {
        var word = Console.ReadLine();
        var str = Console.ReadLine();
        var ts = "" + str;
        while ((str = Console.ReadLine()) != "END_OF_TEXT") ts += " " + str;
        Console.WriteLine(CountOf(ts.ToLower(), word));
    }
}
