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.
