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;
using System.IO;
using System.Collections.Generic;
namespace aoj{
	class program{
	
	static void Main() {
		string find=Console.ReadLine();
		string str=Console.In.ReadToEnd();
		FindStr fs=new FindStr(find,str);
		Console.WriteLine("{0}",fs.find());
	
	}
}

class FindStr{
	string src;
	string dst;
	public FindStr(string s, string d){
		src=s;
		dst=d.Substring(0,
		d.LastIndexOf("END_OF_TEXT",StringComparison.OrdinalIgnoreCase));
	}
	public int find(){
		int count=0;
		int index=0;
		while(true){
		if((index=dst.IndexOf(
		src,index,StringComparison.OrdinalIgnoreCase))==-1)
			break;
			count++;
			index+=src.Length;
		}
		return count;
	}
