• From the following table, find the highest decimal value v that is less than or equal to the decimal number x

and its corresponding roman numeral n:

1	I
4	IV
5	V
9	IX
10	X
40	XL

1	36	10	X	X
2	26	10	X	XX
3	16	10	X	XXX
4	6	5	V	XXXV

1	2012	1000	M	M
2	1012	1000	M	MM
3	12	10	X	MMX
4	2	1	I	MMXI
5	1	1	I	MMXII

Example #3

x = 1996

Iteration #	Decimal number (x)	Highest decimal value (v)	Highest roman numeral (n)	Temporary result
1	1996	1000	M	M
2	996	900	CM	MCM
3	96	90	XC	MCMXC
