Leetcode Problem(Easy) Roman to Integer

By
  Roman numerals are represented by seven different symbols:  I ,   V ,   X ,   L ,   C ,   D   and   M . 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 ones 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 an...
