Roman To Integer | Leetcode 13

[@aniketbasu3865]

the code is referring to an out-of-bound index for the loop. ``` int val = 0; for(int i=0;i=mpp[s[i+1]]){ val += mpp[s[i]]; } else{ val -= mpp[s[i]]; } } val += mpp[s.back()]; return val; ``` this is the correct code

Nice explanation. Also, the code is referring to an out-of-bound index for the loop.

add i

*Superb* 👌 *explanation* *sir*

[@BartleBeez]

What if the number starts with "9"? How do we write "9" in roman numeral?

[@anubhav0355]

Beautiful explanation. Thank You!

[@muditkhanna8164]

use i =1for loop and check for i-1 and i

[@ravikumar-gp6ui]

sir,one test case is not running in this code class Solution { public: int romanToInt(string s) { unordered_map mymap{ {'I',1}, {'V',5}, {'X',10}, {'L',50}, {'C',100}, {'D',500}, {'M',100}, }; int result=0; for(int i=0;i

[@aryanpawar7788]

{'M',100} shd be 1000
