Read a roman number and convert that into decimal. For such a problem we have to find a suitable solution. we need to write a method to read the Roman number and a converter. there is a common patterns in Roman numbers and find a solution to convert.

For example , " III "means 1+1+1=3 , " V " means 5 " IV " means 4 how ?

let see , First read string and check from back to front .so now we have first " V " and " I " .now check last character is grater other one then " - " operator else " + "operator ( if V > I then 5 - 1 = 4 )

#### Example :

" IX " "1" "10" this mean 10 > 1 then 10 -1 =9.

" XIV " "10""1""5" this mean 4 >1 so 5-1 = 4 and renaming 10 ==>10+4 = 14

#### Roman To Decimal

#### When you run the program, the output will be:

Enter roman number you want to convert

Command End to stop entering

i

I is equal to 1

iv

IV is equal to 4

ix

IX is equal to 9

xii

XII is equal to 12

xiv

XIV is equal to 14

c

C is equal to 100

xc

XC is equal to 90

m

M is equal to 1000

cm

CM is equal to 900

xm

XM is equal to 990

End
