string roman_conv(int n) {
    switch(n) {
        case 1: return "I";
        case 2: return "II";
        case 3: return "III";
        case 4: return "IV";
        case 5: return "V";
        case 6: return "VI";
        case 7: return "VII";
        case 8: return "VIII";
        case 9: return "IX";
        case 10: return "X";
        default: return "Invalid Input";
