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.

Example

Input

END_OF_TEXT


Output

3
#include <iostream>
#include <string>

void tolower (std::string &s) {
	for (char &c : s) c = tolower(c);
}

int main() {
	std::string s, t;
	std::cin >> s;
	tolower(s);
	
	int ans = 0;
	
	while (true) {
		std::cin >> t;
		if (t == "END_OF_TEXT") break;
		tolower(t);
		ans += (s == t);
	}
	
	std::cout << ans << '\n';
	
	return 0;
}
