# c++ Direct easy to understand Brute Force Solution

• If you observe there is a specific symbol to represent a particular digit in units place, tens place, hundred's place and thousands place.

In the below code I am iterating through the digits from unit's place to ten's place and so on.

When i reach the highest digit place i start printing that particular symbol and return .......till i reach unit's place.

``````class Solution {
public:
string s = "";
string intToRoman(int num) {
store(num,0);
return s;
}
void store(int num,int i){
if(num == 0)
return;
store(num/10,i+1);
int x = num % 10;
printrom(x,i);
}

void printrom(int x, int i){
string t = "",f = "",n = "";
if(i == 0){
t = "X";
f = "V";
n = "I";
}
else if(i == 1){
t = "C";
f = "L";
n = "X";
}else if(i == 2){
t = "M";
f = "D";
n = "C";
}else if(i == 3){
n = "M";
}
switch(x){
case 1:
s += n;
break;
case 2:
s += n+n;
break;
case 3:
s += n+n+n;
break;
case 4:
s += n+f;
break;
case 5:
s += f;
break;
case 6:
s += f+n;
break;
case 7:
s += f+n+n;
break;
case 8:
s += f+n+n+n;
break;
case 9:
s += n+t;
break;
}
}
};
