    I dont know what's happening with this compiler, it's always giving me an error message. Not even a message about the syntax or the exercise...it just yields some hexadecimal values on the screen with the std error messages

    I used the sstream object to convert a string to an unsigned long long , but the value the compiler expects is so large, it's fitting just the largest number unsigned long long can hold...

    Why is std::stoi() not working?

    I dont know why I'm getting an error, actually, a timeout or whatever error, it's not even checking...I tried it on another compiler and it totally worked...it's not working here though!

    I dont know whats wrong, I did a for loop that checks conditions for the Roman letters and would assign the integer += the value of this letter, but for some reason it doesnt work, and I == 1 , V == 5 but in the test case IV is 4...
