I know s is the string of roman numerals but because I don't know what i stand for, I am not sure what s[i] means. I am trying to understand the solution that is posted line by line, but am stuck with this specific part. All help is appreciated, I understand the roman numeral system fully.

problem attached

"i" is the index of the character being examined in "s". Index starts at 0.
"total" is an accumulator. It is the sum of values of each roman character.
