[Python] Арабские числа в римские. Решаем логические задачи на Python вслух #2

# Symbol Value # I 1 # V 5 # X 10 # L 50 # C 100 # D 500 # M 1000 # For example, 2 is written as II in Roman numeral, just two one’s added together. # 12 is written as XII, which is simply X II. The number 27 is written as XXVII, # which is XX V II. # Roman 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: # I can be placed before V (5) and X (10) to make 4 and 9. # X can be placed before L (50) and C (100) to make 40 and 90. # C can be placed before D (500) and M (1000) to make 400 and 900. # Given an integer, convert it to a roman numeral.
