The provided solution works sufficiently for most roman numerals. Exceptions that have been tested include:

• MCXIX

I believe this is due to the functionality of calculating the value of a roman numeral. The process includes calculating in pairs. One improvement could include ordering the numeric values into pairs.

For exmaple: MM, IX, CC etc. Then find grouping of Roman Numerals. For these solutions that was not done due to code originality.

It was crucial for the script to have the capacity of calculating roman numerals from the base upwards

Working in reverse order could be extremely beneficial, an example includes:

Taking a Roman Numerical Value such as MCIX (Equals 1109) and work in reverse order:

The current script disregards the possibility of a uneven roman numeral such as MCXIX.

The script processes all the pairs:

• MC
• XI

But disregards the deduction of 1 from 10. For example X - I (10 deduct 1) this is because the script handles the last digit by simply adding this to the final calculation.

I hope to further improve this script, as said previously, by pairing as many values as possible and adding all pairs and individual values remaing. I feel this method would be faster performance-wise but more beneficial for more complex roman numeral values.
