49 is IL.

here is pseudo code for converting

const int vals[] = {1, 4, 5, 9, 10, 40, 49, 50, 100, 400, 500, 1000}

const int str[] = {I, IV, V, IX, X, XL, IL, L, C, CD, D, M}

string toRoman(int n) {

string ans;
int i = 11;
while (i >= 0) {
   while (n >= vals[i]) ans += str[i], n -= vals[i]; 
  i--;
}
return ans;

}

Note: I might have missed a digit or two, but you get the gist of it. Just iterate from largest to smallest digit and subtract it from the number while you can.

Edit : didn’t include 900.

You are right, 49 is XLIX.

49 = 40 + 9 = XL + IX = XLIX

I wrote a simple code for this here.

You can find more information here.
Roman numerals were pretty much standardized, but people tend to use their own rules to generate numerals from very past.

Roman numerals are written by concatenating place values of every digit, so it should be XLIX.
