求三色彩球的颜色。有数量无限的红(Red)绿(Green)蓝(Blue)三种彩球排成一行，每组先为5个红色球，随后3

个绿色，最后为2个蓝色。每个球都有编号，从左到右依次为1,2,3……。输入整数代表编号，求该编号球的颜色。下

面是C++代码是实现，正确说法是( )。

1 int N, remainder;2 cin >> N;3 remainder = N % 10; // remainder变量保存余数4 5 if((1 <= remainder) && (remainder<= 5))6   cout << "Red";7 else if ((6 <= remainder) && (remainder <= 8))8   cout << "Green";9 else if ((remainder == 9) || (remainder == 0))10   cout << "Blue";
