#include <iostream>

std::string toBinary(int n) {
    std::string binary;
    while (n != 0) {
        binary += (n % 2 == 0 ? "0" : "1");
        n /= 2;
    }
    return binary;
}

int main() {
    std::string s = "c++ pro";

    for (int i = 0; i < s.length(); i++) {
        std::cout << toBinary(s[i]) << " ";
    }

    return 0;
}
