import java.util.Scanner;

public class LabProgram {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        char ch = in.next().charAt(0);
        String line = in.nextLine();
        int count = 0;
        for (int i = 0; i < line.length(); ++i) {
            if (line.charAt(i) == ch) {
                ++count;
            }
        }
        System.out.println(count);
    }
}

#include <iostream>
#include <string>

using namespace std;

int main() {
    char ch;
    string str;
    int count = 0, i;   // initialize count to 0
    cin >> ch;  // read a character
    getline(cin, str);  // read rest of the line
    for (i = 0; i < str.size(); ++i) {  // go through all characters of line
        if (str[i] == ch) { // if character is same as the first character entered
            ++count;    // then increase count by 1
        }
    }
    cout << count << endl;  // print count
    return 0;
}

if __name__ == '__main__':

    for ch in input_string[1:]:
        if ch == char:
