int main() {
    string a;
    char b;
    int count = 0;
    while (getline(cin,a) , cin >> b) {
        for(int i = 0;i < a.length(); i ++ ){

            if((a[i] > 64 && b > 64)&&(a[i] == b || a[i] - 32 == b || a[i] + 32 == b)) count++;
            else if(a[i] == b) count++;

    }
}
// 64 位输出请用 printf("%lld")
