//num >=0

string convert_int(int num)
{
	IDictionary  numToChar = { 
	{0, '0'},
	{1, '1'}....
	}
	StringBuilder strNum = new StringBuilder();	
	do
	{
		int unit = (num % 10);		
		strNum.InsertAt(numToChar[unit], 0);
		num = num /10;
	}while(num > 0);
	return strNum;	
}

IDictionary  numToChar = { 
	{0, '0'},
	{1, '1'}....
	}
	
string convert_int_recursive(int num, out StringBuilder res)
{	
	if (num == 0)
	{
		return res;
	}
	int unit = (num % 10);		
	strNum.InsertAt(numToChar[unit], 0);
	return convert_int_recursive(num / 10, res);
}
