//code I need Help with:

public static int palindromeCount(String s) {
    int count = 0;
    for (int i = 0; i < s.length(); i++) {
        for (int j = 0; j < s.length(); j++) {
            if (s.charAt(i) == s.charAt(j)) {
            }
            count++;
        }
        break;
    }

    return count;
}

//Given and can't change:

public static void main(String[] args) throws IOException {
    Scanner in = new Scanner(System.in);
    final String fileName = System.getenv("OUTPUT_PATH");
    BufferedWriter bw = null;
    if (fileName != null) {
        bw = new BufferedWriter(new FileWriter(fileName));
    } else {
        bw = new BufferedWriter(new OutputStreamWriter(System.out));
    }

    int res;
    String s;
    try {
        s = in.nextLine();
    } catch (Exception e) {
        s = null;
    }

    res = palindromeCount(s);
    bw.write(String.valueOf(res));
    bw.newLine();

    bw.close();
    }
