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

    int cnt = 0;
    cin >> w;
    cin >> t;
    while(t != "END_OF_TEXT")
    {
        transform(t.begin(), t.end(), t.begin(), ::tolower);
        if (t == w) cnt++;
        cin >> t;
    }
    cout << cnt << endl;
