+%22%22%22%0ARoman numerals are represented by seven different symbols: I, V, X, L, C, D and M.%0A%0ASymbol       Value%0AI             1%0AV             5%0AX             10%0AL             50%0AC             100%0AD             500%0AM             1000%0A%0AFor example, two is written as II in Roman numeral, just two one's added together. Twelve is written as, XII, which is simply X + II. The number twenty seven is written as XXVII, which is XX + V + II.%0A%0ARoman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used:%0A%0AI can be placed before V (5) and X (10) to make 4 and 9. %0AX can be placed before L (50) and C (100) to make 40 and 90. %0AC can be placed before D (500) and M (1000) to make 400 and 900.%0AGiven an integer, convert it to a roman numeral.
