Define a function romanDigitToInt that converts a single Roman digit to a decimal integer. This function takes an argument as a element of the RomanDigit union type and transforms it into the decimal integer using patter matching. This function should have signature: RomanDigit -> int.

let convertRomanToInt romanNumber : int =

match romanNumber with

| 'I' -> 1

| 'V' -> 5

| 'X' -> 10

| 'L' -> 50

| 'C' -> 100

| 'D' -> 500

| 'M' -> 100

let rec romanNumberToInteger romanNumber =

if (String.length romanNumber = 1) then

convertRomanToInt romanNumber.[0]

elif (String.length romanNumber = 0) then  0

else  let atuple = (romanNumber.[0],romanNumber.[1])

let f atuple =  match atuple with

| (f,s) when (convertRomanToInt f) >=(convertRomanToInt s)->(convertRomanToInt f) + (romanNumberToInteger romanNumber.[1..])

| (f,s) when (convertRomanToInt f) < (convertRomanToInt s) -> (convertRomanToInt s) - (convertRomanToInt f) + (romanNumberToInteger romanNumber.[2..])

f atuple

let charToRomanDigit c =

printfn "%c" c

match c with

| 'I' -> 'I'

| 'V' -> 'V'

| 'X' -> 'X'

| 'L' -> 'L'

| 'C' -> 'C'

| 'D' -> 'D'

| 'M' -> 'M'

| _ -> failwith "Invalid Entry"

let stringToNumber str =

let upperDigit (x:string) = x.ToUpper()

let upperString = upperDigit str

printfn "%s" upperString

String.collect (fun c -> sprintf "%c" (charToRomanDigit c)) upperString

let romanNumber = "XIX"

let upperDigit (x:string) = x.ToUpper()

printfn "a: %s" (upperDigit romanNumber)

romanNumber = stringToNumber romanNumber

printfn "\nValue = %d" (romanNumberToInteger romanNumber)

Explanation:

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
