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

Output

3
#include <iostream>
#include <cctype>

int main() {
    int num{};
    std::string w{}, s{};
    std::cin >> w;
    for(auto& c : w) { c = tolower(c); }
    while(std::cin >> s) {
        if(s=="END_OF_TEXT") break;
        for(auto& c : s) { c = tolower(c); }
        num += (s==w) ? 1 : 0;
    }
    std::cout << num << std::endl;
}
