uestion 7: In this question, we will use a simplified version of the Roman Numerals System to represent positive integers The digits in this system are I, V, X, L, C, D and M. Each digit corresponds to a decimal value, as showed in the following table Roman digit Decimal value1 10 50 100 500 1000 A number in the simplified Roman numerals system is a sequence of Roman digits, which follow these 2 rules: The digits form a monotonically non-increasing sequence. That is the value of each digit is less than or equal to the value of the digit that came before it For example, DLXXVI is a monotonically non-increasing sequence of Roman digits, but XIV is not There is no limit on the number of times that 'M' can appear in the number 'D, 'L' and V' can each appear at most one time in the number C','X, and 1, can each appear at most four times in the number 1. 2. For example: IIII, XVII and MMMMMMDCCLXXXXVII are legal numbers in our simplified Roman numeral system, but III, XIV, VVI and CCXLII are not Write 2 programs: a. Reads from the user a number that is represented in the simplified Roman numerals system, and prints it's decimal value Sample output Enter number in the simplified Roman system CXXXXVII CXXXXVII is 147 b. Reads from the user a (decimal) number, and prints it's representation in the simplified Roman numerals system Sample output Enter decimal number: 147 147 is CXXXXVII
